E-SKEPTIC is the weekly electronic version of Skeptic magazine. In November 00, I posed a challenge to E-SKEPTIC readers that was presented to me by an old friend named Randy Kirk, who is a Christian with whom I have had many long discussions and debates about science, religion, and philosophy. That question is What are the benefits of being a skeptic (or nonbeliever, atheist, agnostic, free thinker, etc.); conversely, along the lines of Pascals wager, in Randys words How can the anti-god folks argue that their persuading others away from God, Jesus, and religion is a benefit to them now or in some potential afterlife. All the scientific evidence points to benefits of faith.


Some entries were lightly edited for grammar and length. The response from several believers, and Randy Kirks response, follows at the end.


Why would anyone purposely add the limitations of a superstition to his/her intellect and imagination? As human beings on a backwater planet, our faculties are already limited enough. -Ron LaDow, rwmld@email.com


What does not believing in God have to offer? Nothing. I believe things because Im convinced that they are true, not because they make me happy. If I believed in things to be happy, I would believe in God. -Dan Mason, jlapaglia@hotmail.com

Our ability to feel the affect that might be named transcendence seems to be an emergent characteristic of our species. It appears in all ethnic groups, but with variation among individuals and tempering by culture. Our ability to hold at one time both a rational understanding of something and a faith-based understanding also seems to be an emergent characteristic of our species. An appeal to a religious faith as an explanation for a feeling of transcendence simply diminishes both explanation and transcendence. I have enjoyed a lot more of both since dropping my belief in the personal presence of a god. -Lee Van Slyke, San Clemente


As a student and teacher of anthropology of religion, Ive always been struck by the extreme religious ethnocentrism that is almost invariably inherent in the Pascals wager-like arguments presented by Christian devotees. If they were to take this wager seriously, it would be incumbent on them to apply it to all of the worlds diversity of religions. This would take them into a study of that diversity, and they would soon become aware of the in-depth lack of uniqueness of their particular religion, as well as the contingent nature of their chosen faith. In fact, such a study, if carried out in any depth at all, would leave them little to no time to devote to just one religion! -Leon Albert, lalbert001@earthlink.net


Although my conversion was more discovery than change, I have substantially shed the debris of superstitions, unwarranted assumptions, and attacks on my credulity that characterizes life among the faithful. I feel exhilarated, and even cleansed. At long last (Im 81), a substantial chunk of who and what I am seems to be falling into place. Although I have and will debate/discuss/argue with others, and write letters to editors and to members of the Ohio school board re Darwin v. Design, I think it is fruitless to proselytize. I just enjoy. -Shel Harper, Broadview Heights, Ohio


Ever since the day I became a full blown skeptic, and I was unafraid to announce my skepticism in organized religion and the need to answer to a God who seemed to be very demanding in areas of Love of him/herself, I am now free to live without fear of a Godly damnation and a life of everlasting fear and pain, as described by the Christian religion that I was raised in. I am now prepared to leave this world one day, and I have no fear of the unknown anymore. I am being judged by my own conscience and I still believe that man must assist others when necessary in order to achieve the most important thing that I know of Self Respect. -George Poole, gpoole@adelphia.net


I have embarked upon a journey. An entity whose world was prescribed from beginning to end, where the deepest mysteries are given meanings, and life is promised beyond the grave. Not willingly did I depart, nor yet know the final port. But once underway, there is no turning back. The winds that push me are the sins of manipulation and deceit. Only my ignorance of these practices allowed me to reside in the Promised Land. Awareness began my journey and insight and understanding became my destinations. Is there a benefit to this journey for me or for others? The question is open-ended by not specifying to what end. If your purpose will be enhanced by a close affinity to reality and truth then the dissolution of mythologies is required. If subjugation to pacifistic norms is desirable and rational thinking disruptive then there is no benefit to journey away from the dogmas of religious beliefs. I measure the benefits of my journey through the knowledge and understanding of who I am denied me in that far away Promised Land. -MMantyk@bcbsm.com


My behaviors are now my own. They are not the product of religious guilt or indoctrination, but of my own mind and my own appreciation of that which makes life (all life) great! I am free to appreciate a Muslim, a Buddhist, or a sinner for whom they are, not what they are. When I walk beneath the stars, I can look up and wonder at their origins, while tasking my mind to try and comprehend their endless mysteries. Everything in this world becomes a question, leading to more questions, leading to endless possibilities and thought invoking quandaries. The simplest organism is precious and awe inspiring. Questions and thoughts have replaced faith and dogma. My mind is now free to roam in places once restricted. Where God once imprisoned my mind, atheism has set it free to roam the universe in search of answers...in search of nothing more substantial than a place to roam! -Shawn K. Heflick


There are more than a dozen major religions, many of which profess to represent the true nature of existence. Among these, some describe an afterlife, promising wondrous things for believers, and eternal torment for the rest. Being a believer would mean choosing one of these religions, or possibly personalizing one for myself. In essence, I would be betting on the one that seems most appropriate to me. But what if there were no afterlife? I would have wasted some of the short time I have on this world encumbered by my religions code of conduct. Even worse, what if there were an afterlife, but I had picked the wrong beliefs, thereby vouchsafing for myself eternal torment? In short, the chances of my choosing the right religion and experiencing a wonderful afterlife are slim. Given the further possibilities of no afterlife or eternal torment, I find it best to live my life true to myself. -Jamie Sanderson, jamie@sanderson.ca


Lets separate faith and doctrine. As a person raised in Christianity for the first 18 years of my life, I can tell you that it was a huge relief for me to reject religious belief. I was rid of a lot of guilt and confusion. I am much happier now. Has Mr. Kirk read the Old Testament? How can anyone in their right mind revere a god like Jehovah, who murders, burns, and destroys his chosen people when they disobey him? -james11@rocketmail.com


Freedom to see/hear/feel life through my own experiences, not through the filter of religion. Without religion, I can immediately experience, enjoy, judge and evaluate any experience without first running it through the God filter and deciding how I am supposed to feel. And contrary to what most people think, I find that a greater sense of moral responsibility comes from only having to answer to oneself. -Sheila1


Benefits to being a non-believer in the supernatural


1. You are constantly searching for meaning and the truth since you do not settle for the god did it, it was a miracle, God has his own (not-understandable by mortals) reasons, etc.


. You believe that everything is explainable in principle, and the only difference between a miracle and a natural phenomenon is that you are not able yet to explain the former in natural terms.


. You do not feel compelled to teach your children a dogma of any kind other than to think freely and to push the limits of knowledge. There are no questions that need to be silenced, ignored or dismissed as an attitude problem. It makes it okay to answer, I do not know to many of the great questions in philosophy.


4. If, in the future, a more technologically advanced civilization learns about our rituals and myths they may want to enslave us by putting on a Second Coming show, or impersonating Buddha, Jesus, Mohammed and the like. That will not work with skeptics.


5. You are more likely to like and understand science because it will not conflict with your belief system since it is your belief system.


6. Your moral values are not based in a reward and punishment system and the complexity of morality is more apparent to you than to those that believe it was handed out to them by a being that supposedly knows best.


7. You do not blame the devil for the bad things that happen to you, you do not thank God for the good things that happen to you. You understand the statistical nature of events beyond your control and you take responsibility for your own mistakes if that is what caused the bad thing to happen and thank yourself and your teachers (parents, friends etc.) for the good things that are a direct result of a good decision you made.


8. You live life to the fullest because you do not trust there is life after death. You have obvious reasons to work on making this world a better place. You acknowledge that nobody really knows what happens after you die so there is no reason to see death as a good or a bad thing for the individual that dies and definitely as a bad thing for those who are emotionally attached to that individual.


. You have no moral quarrels with the advancement of medicine and the extension of life because if this is it, you may want to stay around a bit longer.


10. From my personal experience I have found that I am more likely to have friends belonging to different faiths than someone that feels compelled to stick to their own kind. People also tend to speak their minds more freely around you. -Jose H. Diaz, jdiaz100@cox.net


We need to first clarify the question by making a few distinctions and definitions. Skepticism does not necessarily equate with non-theism. Skepticism is essentially a way of forming and evaluating beliefs, in philosophical terms, an epistemology, plus perhaps an associated ethics of belief. Skeptics believe that in matters of the intellect we ought to follow our reason so far as it is possible. This means keeping an open mind and basing your beliefs, so far as possible, on the total evidence. None of this necessarily precludes belief in God or an afterlife. It may be that most skeptics are non-theists and doubt the possibility of an afterlife. If this is so, this is a contingent matter of fact-it just so happens that, in reality, there is no credible evidence for the existence of God or an afterlife (and perhaps rather strong reasons for doubting both). A second and essential point is that if someone is a non-theist, he or she ought to adopt that position because it is the truth (or the most likely to be true given what we know). It is a mistake to think that we ought to either believe in God or not believe in God because of the psychological benefits of doing so (or not doing so). So, in answer to the question Why should I be a non-believer? the response should fundamentally be, because that is the truth, and you ought to believe the truth-this what rationality requires.


Someone might say that the existence or non-existence of God is not a matter of the intellect but rather of the heart, of the emotions, of faith. My response is that going this direction leads us to nothing but a quagmire of incompatible positions that all claim to be based on faith or feeling, for if reason can give us no guidance, what is there to indicate that any one faith is any better than any other? Reason is and must be the final arbiter of truth. Having said all this, I think it is a misconception that a non-theistic, non-religious worldview must be bleak and depressing. The universe may be contingent and it may have only the meaning that humans give it, but why should this be so terrible? There is abundant awe and wonder in the natural world for those who are willing to see it, and the achievements of humankind, while finite and fragile, are achievements nonetheless. As Bertrand Russell once wrote, Happiness is nonetheless true happiness because it must come to an end, nor do thought and love lose their value because they are not everlasting. -Shawn Dawson, sl.dawson@sk.sympatico.ca


One benefit I derive from my nonbelief in a God or gods is the satisfaction of being honest with others and myself. Intellectually, I find the proposition of the existence of God or gods fantastic, to say the least, and about as likely as being true as of there actually being leprechauns. I began feeling this way at an early age, but because I was raised by fundamentalist Christians it took me many years to own up to my own brain. It also took me time to develop my thinking skills to where I could make such decisions rationally and objectively rather than based simply on emotion, as I was raised to do. Years later, I can finally say, I am an honest person-I admit that I do not believe in God, Zeus, Osiris, or any other such supernatural entities.


A second benefit I derive is freedom-freedom from fear of being watched by the All-Seeing Eye of God who watches and judges everything a person does; freedom from the rules and dictates of the writers of the Bible thousands of years ago whose motives, morals, education, and very identities are unknown. I remember distinctly the terrifically joyous feeling I had when I finally admitted to myself that there was no God! I was finally free of all the superstitions, rules, tired aphorisms, and nonsense that is organized religion. I could be my own person, act by my own humanist beliefs, and finally enjoy life instead of spending my time worrying about death. And I was free to find my own meaning to my life rather than blindly adopting someone elses.


A third benefit, and possibly the most important, is that, by ridding myself of a belief in God, I gained a firm ground in morals. The moral foundations of deistic religions are based on the might makes right principle God says it is right to do X and wrong to do Y, and since God is bigger than you and me, we have to do what God says. Read the moral tenets of the Bible; you will find no justifications or explanations. The only ground for the moral teachings of the Bible is Do this and dont do that because God says so. The religious weltanschauung is that people are puny, miserable wretches (as in the song Amazing Grace) and God is the King of the Universe, so God has all authority to make the rules, reward his followers, and stamp out the ingrates as He sees fit. According to this view, humans only need to be good to each other because we are ordered to do so, not because we have empathy for other beings, or because we care for them, or because we recognize that we are all part of a mutually dependent society, or any other number of good reasons for being kind to one another.


Since throwing off the yoke of such teachings, I have developed an understanding of humanist ethics and found that my morality is much stronger and more honest because it is based on personal intellectual rigor and personal enlightenment rather than through mindless, blind obedience. -Jon Puro, puroj@pcez.com


Isnt being committed to the truth, wherever it leads, the only way an intellectually honest person can live? This is an inherent benefit for living the way of the skeptic. Im less susceptible to being conned because I want to see the evidence. Skeptics understand human life is special because of our human values and high human aspirations, not because of some sadistic God who made things the way they are. Thus skeptics are more inclined by nature to solve their own problems, because we know there is no man in the sky who is going to take care of us. We know that turning things over to God basically means doing nothing. Being a skeptic means being a mature adult who takes responsibility for his or her own life. How could any adult person make a conscious decision to live their life any other way? -William Winston Newbill, Arlington, Texas, Newbill@aol.com


As the webmaster for one of the oldest personal websites on the net devoted at least in part to skepticism (www.bidstrup.com), and one of the busiest (over 4,000 reads per day), I get a lot of email on this question, and have for years, and have become quite practiced (and rather brutally frank) at providing an answer. This is what I tell religionists, who of course are primarily Christians, who ask me that question


First, I must say that the universe is quite coldly indifferent to what us mere humans wish to believe. Belief for the mere sake of belief, is, in my opinion, nothing more than a form of mental masturbation, and about as useful in enriching our lives-reality doesnt care what we want, so belief based on nothing more than a desire to believe accomplishes absolutely nothing in terms of approaching the truth as to the nature of the universe and our place in it. If we are descended from pond scum, then the reality is that we are descended from pond scum, and all the angst of a Woody Allen, the abhorrence of a Benjamin Disraeli, or the sneering contempt of a Duane Gish would not change that reality. Indeed, all the centuries of religious mysticism and, frankly, wishful thinking, have accomplished very little human progress in comparison to the four centuries that have elapsed since the Enlightenment, which in its philosophical basis is essentially a rejection of religious mysticism in favor of a reliance on human faculty in discerning the nature of reality. When Christianity ruled the world, we called it the Dark Ages, and our rejection of religious rule of both the political and natural sciences has come to be called the Enlightenment. Why, then, can we not recognize and accept what this tells us about the nature of religious belief, and the usefulness of religious doctrine in the governance of our lives?


Second, as a matter of personal comfort, I find that a belief in the best description of reality I can discern (while recognizing its limitations), however indifferent to my circumstance, is far more comforting than belief in a set of doctrines that demand that I worship a narcissistic god, or obey an arbitrary one. This is particularly true when I contemplate the vast variety of dogmatic systems, most of which are mutually exclusive, but nearly all of which demand my acceptance of their doctrinal exclusivity. If a god exists, that god has allowed an intolerable degree of confusion as to its nature and the manner in which its existence is to be honored, worshipped or observed. Such an intolerable confusion, without a single shred of evidence as to which, if any, are correct, represent an unacceptable injustice on the part of a being usually described as omnibenevolent. How can this be?


Third, the arguments for a belief based on the desire to believe strike me as essentially infantile, like the child who believes in Santa Claus only because the notion of a magical being who can provide him with the toys he wants is comforting to him. One of the quintessential elements of maturity is the ability to recognize, accept and face the world as it really is, not as we wish it to be, and to make an exception in the case of religion is neither an example of maturity nor is it flattering to our belief in ourselves as rational beings. Why then, do we congratulate the growing maturity of our children when they abandon their belief in Santa Claus, and yet insist that they accept what is in essence, a grown-up version of the same thing? Is not a mature acceptance of an uncomfortable reality better than the acceptance of a warm and fuzzy fantasy?


Fourth, I find it much more satisfying to assign the meaning to life which I wish to assign to it, than have it assigned for me by an arbitrary doctrinal system, which has only a very tiny chance at best of being factually correct (only one of the many thousands of mutually exclusive doctrinal systems can possibly be correct). When I was born, the meaning for my life is a blank slate, and I thank the Universe for that! It means I am quite free to assign the meaning I choose, and to make whatever contribution to the world I am capable and desirous of making, or Im equally free to make none at all if I so desire. It is the ultimate in personal freedom, and I find that notion to be deliciously satisfying! Theres no being standing over me with a whip telling me to do this or that; rather, there is instead the freedom offered by my own sense of self esteem and self worth directing me to make the contribution that I choose, based on my own talents and interests. So why would I prefer to have the meaning to my life arbitrarily assigned to me by a doctrinal system that, with almost absolute statistical certainty, is arbitrary itself?


The reason that it is urgent that we abandon our religious dogma is simple human justice and intellectual and social progress demand it. -Scott Bidstrup


The freedom inherent in the view that there is nothing preordained by an omniscient entity is supremely liberating. However, my agnosticism allows more. At heart I am a physicist. I truly enjoy the contingent aspect of scientific knowledge. It is possible that one day a new theory will be announced that, in a completely novel way, accounts for some aspect of reality better than what we have now. The twin revolutions of Relativity and Quantum Mechanics did this. Each changed our views of reality in fundamental ways and allowed us to extend our understanding, and thereby our control, of whole ranges of phenomena. As we learn we see reality in entirely new ways and we can use this knowledge to create a better world.


The meaning of life is found in our contributions to the sum total of human culture. For me this is far more fulfilling than following the dictates of an omniscient and omnipotent whatever. Without a god the struggle produces something that could not otherwise be. -Leonard Tramiel


I take great satisfaction in knowing there is no all-powerful invisible man living in the sky whos just waiting for me to step out of line. What a terrible thought that gods might actually exist and that we would be powerless before them. Christians and other religious people say we need moral laws handed down from a higher power, with fear of eternal consequences if we dont obey. Otherwise were free to just act on any notion that pops into our heads. So what of gods in that case? What are they but beings with no higher power telling them what to do, and no fear of any consequences? Gods can act on any selfish, outrageous whims that they want, and we would be told to obey or else. I take great comfort in the lack of gods. -Burt Ward, Skyflight@Decepticon-Empire.org


The first question we have to ask ourselves, before we ask anything else, is whether it is more important to us that our beliefs are as true and accurate as we can make them-or whether it is more important to us that our beliefs work in our lives, that they provide us with comfort, reassurance, and a sense of identity and meaning. What is true and what we would like to be true are not always the same, and many false beliefs will work for the people who live happily by them.


To ask the question what are the benefits of being an atheist, agnostic, skeptic, etc. is to implicitly begin from the assumption that what matters most is ones personal comfort, not truth. If this really is your ultimate standard-and if your choice does not clash with the happiness and freedom of anyone else-there may not be any point in telling you that youre wrong. But by the same token, you cannot tell anyone else that they are wrong-there is no wrong by this standard.


The beginning of wisdom is a love of truth, the Greeks once wrote. I agree. -Sue Strandberg


Liberating is the key word. You dont have to choose sides, and belong to a group that is in competition with so many other groups that claim spiritual superiority. From this outsiders vantage point, on balance, so much competition and conflict between religions outweighs their usefulness.


When I was growing up in Pasadena, I remember the great emotions of cheering our football team in the homecoming game against the hated cross-town rivals. Looking back on it, I was so emotionally invested in the fortunes of my high school team that I really believed we were better than our rivals.


A year or two later I happened upon a homecoming game in a nearby town. Suddenly I realized that my emotional investment in the fortunes of my home football team was entirely an accident of where I happened to go to school, not a function of how good or deserving my team was. If religious people recognized that the particular beliefs they hold are most likely simply a function of where they happened to grow up, perhaps the diminished emotional intensity of their religious experience-presumably a minus to them personally-would result in less conflict with other religious people. -Ralph Leighton, tuva@sprintmail.com


For the secular mind (a term I prefer to atheist or nonbeliever), life is much more comprehensible and simple. The ancient, clouded beliefs fall away to reveal the vast splendor of nature, of existence, the preciousness of being alive, being conscious, of being sentient. This experience is not mediated by the belief in a higher power; it is direct and very powerful. For some, it is almost too much to bear. Life may become poetry, but not everyone is a poet. Some may fall in love with nothingness and some may wish they had never been born at all.


In place of trying to puzzle out the hopeless mystery of Gods justice, a very human morality emerges that strives to make our lives better. Morality is something man does for himself and it is mans sense of fairness that drives it as well as all forms of government or systems of justice. Human moral systems are imperfect, but they have been continuously improved with experience.


The secular mind feels at ease among other animals and life on this planet and accepts our place in the greater scheme of things. For some, family may become more important that fame. For others, pleasure may no longer be deferred for an afterlife. The realization dawns that each individuals sense of purpose is independent of the workings that resulted in the individual, that the meaning of human life is for humans to determine and no one else. Men at some time are masters of their fates The fault, dear Brutus, lies not in our stars, but in ourselves.… -John Howard, Silverlake, California, JoHo44


Why am I an atheist? Life makes more sense this way. Think of all the big questions Why is there pain? Because things happen that dont work well for us. For instance, natural disasters dont usually work for our advantage. Also, diseases tend to hurt us. They arent out to get us. Theyre just doing their thing, which we happen to dislike rather strongly because it interferes with our goals. Since the universe was not designed with us in mind, this makes sense.


Why is there evil? There isnt. There are just people who do bad things. There will always be people who would rather break the rules than follow them, and those people will always hurt others and themselves.


Why do good things happen to bad people, and bad things to good people? Because life isnt fair. If no one is upstairs keeping score, then there is no one upstairs to screw up and make bad things happen to good people, or vice versa. This makes sense in a world without a god. Regardless of whether there is or is not a god, life is still the same. Imagine A Christian and an Atheist walk down the street together. Regardless of what they see, think, feel, or say, theyre still walking down the street together. Its the same existence for all of us, and what we believe about it doesnt change it. If God had wanted us to worry about the intangible, God wouldnt have put us in a tangible world. -Peter Wall, peterj@madnet.net


Nice question, but as pointless as the opposite one, What benefits are there in believing? Yes, one can find rational explanations for believing in God (or any other esoteric phenomenon), like consolation or Pascals wager. Quite correctly various philosophical and theological thinkers pointed out that none of these can be a basis for individual belief-you either do or dont. I am not looking for a benefit in my non-believing. I actually prefer Douglas Adams position, calling myself a radical atheist who is deeply convinced that there is no such thing as God except in the mind of people choosing the easy way to interpret the world. When they ask, But how can you live in a world you presume to be without a meaning, an aim, they show that they cannot fathom to give meaning to their life themselves. Skepticism does have benefits in that people have to look at the world and decide for themselves, which means to be non-partisan and tolerant of others (until they threaten ones own tolerance and life). -Dierk Haasis


First of all, for me, Pascals wager is a profoundly cynical and calculating approach to Christian belief. Its basically a rational-choice, cost-benefit analysis of a conviction that comes to people-if you believe religious people-non-rationally.


What is more, Pascals Wager comes from a Christian perspective, which believes in the persistence of the personality in immaterial form after death, and reward or punishment for that immateriality. Pascal, after all, lived in a monolithically Catholic culture. From this cultural perspective, Pascals Wager makes sense because of the tacit, culturally conditioned acceptance of the possibility of eternal punishment in a hell. But when one understands that the existence of an immaterial soul, a heaven, and a hell are not self-evident, but merely culturally and historically contingent beliefs, the rationality of Pascals Wager disappears.


As to the second question, I find myself puzzled. If Christian faith can be shaken by rational examination of beliefs, then it is not really much of a faith. To charge atheist thinkers with destroying the faith of Christians insults Christians. Are the minds of Christians so weak that the merest whisper of rational enquiry can shatter their worldview, and rob the universe of its wonder? This, it seems to me, was formerly the position of Catholic cultures; therefore, free expression was suppressed.


We no longer live in a culturally or religiously monolithic culture. Christians must accept this, and expect to face challenges to their beliefs at every turn. Otherwise, they can choose to sequester themselves from the hurly burly of American public and academic life. But the impulse to suppress our societys freedom of thought and expression in order to safeguard the religiously faithful is at the core of the dangers of fundamentalism, and from this danger springs a great deal of my repugnance for it, be that fundamentalism Christian or any other kind. -Carol Ann Wald, C. Phil., UCLA Department of English, wald@humnet.ucla.edu


The benefit comes not so much from not believing itself but from the process that might lead one to nonbelief discovering, through the proper study of history, nature, and human nature, the fundamental fact that we are all prone to latching on blindly to such dogmas, be they religious dogmas or political or social ones. It is not through atheism itself that one is freed from these shackles, for atheism can also be a kind of dogma, if embraced for cynical, ideological reasons as it often is. It is rather through the methods and the intellectual honesty that comes from a true study of human history, reason, and science that one is best equipped to free oneself from all dogmas, and to embrace the challenge of discovering new mysteries for the sake of the inquiry itself, without concern about where the inquiry might lead, if anywhere at all. Finally, such a realization has broad applications in all aspects of life, including politics, business, social, and family life. The courage to be wrong, an awareness of the frailties of our intuitions, and the willingness to accept mystery are always our best guides in life, and provide us with a deep strength in the humility inherent to such principles, as contrasted with the seductive sound-bites offered by religious doctrine which lead only to hubris. -Gerry Ohrstrom, gfohstrom@aol.com


You cannot think freely within the frameworks of religious faith anymore than you can judge fairly with the prejudices of a bigot. Loss or lack of faith opens up more questions than it answers, of course, but that is the point. What is the point of god other than to provide psychological comfort for those who do not need answers? I really dont see its value to society. The benefit of nonbelief is a much larger, much more interesting world. As a non-believer I know that the consistent and reliable physical properties of matter control my existence, not an unpredictable deity whose actions and motivations can only be characterized as mysterious. I can study science and better understand how I affect and am affected by the world around me. Studying god, at best, allows me to understand the human process of rationalization. -Bill Henske


I often wish that I could believe in a god, but alas, one cannot make oneself believe something when your logical mind cannot perceive any evidence to support it. It seems to me that it is (or should be) a high moral principle to always seek the truth. This is the only justification that I have for the value of my non-belief. The god story has no justification and panders to the strong feelings that humans have for purpose, life after death, and someone to watch over them (i.e. it is most convenient and emotionally attractive). Nevertheless, I wish I could believe it and I would not want to convince others to abandon their faith. If it helps them get through life and doesnt hurt anyone else, well, thats good for them. (I feel the same way about drugs.) My only concern is when they begin to 1. violate my moral principle (Seek the Truth) by denying the knowledge that science has provided and attempting to convince others of the validity of conflicting religious interpretations of the physical world (e.g. Creationism), or . imposing their moral values on others (e.g. homophobia, dress codes, suppression of alternative views, censorship). Otherwise, Let them enjoy their lovely delusion. -Allan Ferrenberg, Bishop, CA


Faith in religion is a mask that prevents a person from seeing the world and the universe as it really is, rather than the way he or she or someone else thinks it should be. Scientific findings that conflict with the tenets or dogmas of religion, such as on the origin of the universe, life and evolution, will not be accepted objectively, on their face, without emotional bias. A religious person thinks that religion has some truth to bear on topics like these, but that is false. Different religions across the world would claim knowledge of the answers to the specific questions in such fields, but these answers are not derived from empirical evidence. They are what someone once thought they should be. Not only are they at variance with sciences answers, they dont agree with one another either. So there is a Christian origin story, a Moslem one, a Hindu one, a Taoist one, etc.


Science doesnt work like this. It doesnt care what someone thinks things should be. The answers it derives are based on time-tested heuristics known as scientific methodologies, in which empirical evidence is used to get answers in a manner as unbiased as humanly possible. We speak of American religion, Arab religion, Chinese religion, Indian religion, and so forth. There is no such division for science. How science is done anywhere in the world is the same, and American science is not in any way different from Indian science.


Giving up religion changes your whole way of thinking. Religion relies on dogma and authorities for answers. Science relies on empirical evidence, looked at and considered as objectively as possible. A theist approaches problems with the mindset of, What does my religion have to say about this? A skeptic and scientist instead seeks to understand the problem by finding as many facts as possible and then connect those facts to the problem as objectively as possible. The non-theist therefore can deal with the world as it really is. The theist deals with the world as he or she thinks it should be. -Ron Ebert, ron.ebert@ucr.edu


The benefits of faith, whatever they are, ring hollow if they are based on a faith in something that doesnt exist. The related benefit of disbelief is the satisfaction of being courageous and intellectually honest. We must see what is true and then deal with the consequences-we cannot choose what we would like to believe based on the benefits of the belief itself. I frequently hear the argument that I should change what I believe to achieve some end-to avoid going to Hell or to live a happier life or whatever. The bizarre thing about this argument is the implication that I can choose to believe something just because I stand to gain by doing so. I know that the Earth revolves around the Sun. If you promised me a million dollars to change that belief and accept that the Earth is the stationary center of the universe, I might want to change my belief, but I dont think I could, no matter how hard I tried. I could say I believed it, I could act like I believed it, but I couldnt really believe it. - Mark Gilbert, markgilbert@pobox.com


What are the benefits of non-belief and skepticism? Well, what are the benefits in non-belief and skepticism in Santa Claus? When the Santa myth becomes unsustainable, adults teach children that being good is its own reward. We teach them that being law-abiding will keep them out of trouble with society; we teach them that doing unto others will help them remain loyal to their friends and acquaintances; we teach them that holding true to their principles will keep them out of trouble with their psyche. We tell them that if they do this all year round, they will not need a Santa to deliver presents on December 5th. Losing your belief in a Santa who convinced you to behave as a child did not cause you to issue moral wagers about Santa! Why is that? Whether you believe in God or not, bad things happen to good people and good things happen to bad people. Believing in God does not change that. Modern societies recognize that throwing virgins into volcanoes will not enhance crop production. Why would God create rules for a physical universe that are so observable and logical but not create rules for spiritualism that are just as obvious? As I ask all my religious friends If I can be a good person without religion, what are the benefits of belief and dogmatism? -Susan van Druten, Duluth, MN


There is a selection bias at work here. Randy is ignoring the countless people suckered out of income that they cannot afford to give, countless people birthing children they cannot afford to feed, countless people suffering from diseases that they are believing on God to cure. There are plenty of instances of people throwing away their insulin at a healing rally and promptly suffering diabetic collapse.


There might be some scientific evidence pointing to some benefits of faith, I suppose, but I think we could probably dig up some to the contrary-particularly faiths that encourage people to live life in guilt and fear and to deny that this is what they are doing. Not to mention things like bible-sanctioned child abuse (the blueness of a wound cleanseth away evil etc). But the real benefit of nonbelief is one that todays me-first generation might not be able to appreciate. Its not the immediate benefits to the individual that are the most important nonbelief has created a better society. Public health, science, and tolerance-all these things came about in the west as people began to reject reliance on faith and revealed religion. Compare the life you live today with that of the dark-age peasant. Thats what nonbelief has to offer and has delivered. -pmurray@bigpond.com


To me the benefits of being a skeptic and nonbeliever in religious nonsense is that I am not burdened with believing things that are demonstrably untrue or very likely untrue. Ones beliefs tie in to other beliefs; for example if one believes in non-physical entities (spirits) that can interact with the world, it sets you up for various other goofy notions. I think you can waste a lot of time and mental energy dealing with unjustified beliefs. But fundamentally, I value truth. I want to know the truth of the way things work. I know that despite the attempt to winnow my beliefs, there are some things I believe that will later be shown false. But I definitely dont want to bother with quite obviously failed hypotheses. I echo Laplace. On another tack, I dont think that I feel more than the usual existential angst, and indeed I get quite a bit of enjoyment out of life. I also dont notice that religious people are any more serene about this than I am, despite their often proclaimed belief in an afterlife or the comfort of belief in a father like god. If there are negative consequences for your life in being a skeptic (more likely to be social than existential), well, you just have to live with them. Unbelief offers the freedom to roam intellectually, unbound by dogma. -Richard Thomas, University of Puerto Rico, San Juan, PR, rthomas@rrpac.upr.clu.edu


Not believing in God, in an afterlife, in a premeditated decision to bring human beings as a species into existence can initially have the appearance of a cynical, bleak outlook on life. The more that the implications of this view are examined however, the less hopeless it shows itself to be; the more it becomes apparent that not only is there room for hope, it is a necessary outcome of critical thinking. Not a vague, undemonstrated, unlikely form of hope, but real hope with a backbone. Demonstrations of the power of empirical evidence tell us we are getting better at working through problems that at one time we could find no way of positively addressing and therefore harbor no real hope for solving. We had the option to simply want to decrease infant mortality, to communicate quickly with people from around the world, to understand our place in space and in time. As it happened, we found that addressing questions like this had a fruitful direction to take.


What was the trade-off? We bartered false hope for longer life, ways to reduce pain in that life, fruitful methods to find out about nature and in so doing discovering ways to approach a highly varied manner of problems and desires with a real chance of making a positive impact. Yes, problems came up to. The environmental ones, the awful potential for mass extinction that our weapons make possible, grossly unnecessary animal experimentation. But there is a way to deal with these problems. We could want them to solve themselves or we can look at reasonable methods of addressing each of them. We can throw our arms up asking why God let another tragic event occur and pray for forgiveness, or we can work on preventing future tragedy with sound methods. That is real power.


I am throwing ethics into this because science itself needs help on what to do with its power. Do you want someone to interpret then act according to a book that can be seen as condoning killing for belief or non-belief in its particular version of God; or would it be better to come to ethical decisions using an informed intellect that finds the mentioned course of action to be unacceptable? Indeed, if there were an afterlife, then the taking of a life should cause no real grief if the deceased were a good person. Its easier to take life for granted when you have something even better coming afterwards.


If this life is the only one we are getting, and there is no evidence that this is not the case, how much more appealing this life is! There is no longer a resistance to troubling scientific findings like evolution. Now you can experience that facet of nature as the true and amazing phenomenon it is. Knowing that you didnt inadvertently make a mistake that will cause a vengeful God to stick you into a place where you are horribly tortured for eternity also has its psychological perks. Could there ever be a case where I would find it unnecessary to let my skepticism be known? Well, picking my battles, I would probably not hold this debate with someone that was on their deathbed who thought they were going to heaven. There may not be enough time for them to come to terms with these ideas where they would have had a chance to if told earlier. There are other cases, Im sure, but it is an overwhelmingly positive, indeed necessary, thing to come to grips with reality, or at least attempt to get as near to it as we can, if we hope to make positive changes in the real lives we have. - Scott Armetta


Having grown up in a skeptical family, I was surprised to find, when I joined various humanists groups. How bitter many of the members were toward religion. I think that the reason that surveys of church members find them happy is because the others have left. And they left because the teachings of their churches crippled their ability to love and accept themselves, because their churches made them feel guilty about ordinary human sexuality. Most of the humanists I talk to say that giving up the idea of a god has given them the joy of appreciating life, knowing that the time to be happy is now.


Another point is that you give up the constant cognitive dissonance that religious people live with. Many people I know who still attend churches say that they put aside the conflicts between science and religion by putting them in separate compartments. They know that the Bible is a collection of old myths cobbled together by a relatively primitive society, but they still want to focus on the beautiful teachings and visions that are mixed into the stew. I dont believe that this really works for anyone. I dont think it works for anyone when there are really difficult moral and emotional issues to be resolve. I think when a child dies, a spouse leaves or suffers horrible illness, the false comfort of belief fails and people face the same struggle to find interior personal strength that atheists do.


I think that skeptics appreciate the mysteries of the universe more because we dont make up answers. Skeptics know that we dont know everything. We understand Hamlets charge that there are more things in the heavens and earth than are dreamt of in our philosophy, but we dont believe that making up answers solves any problems. This may deprive us of a false sense of security, but it may enable us to be more successful at finding workable and realistic solutions. -Judith Daar Berkeley, Secular Humanists of the East Bay


Benefits of nonbelief include


1. Authenticity. An atheist does not have to stifle inevitable perceptions of the absurdities present in religious teachings and rituals. (For instance, atheists do not weekly utter and lead us not into temptation while suppressing the question of why they are worshiping a God who would tempt them into wrongdoing unless begged not to.) An atheist does not answer, yes to the question, Do you believe in God? while silently thinking, but probably not the God you think Im affirming when I say that, and certainly not the God preached from the pulpit of the church I attend. Few of us-whether believers or nonbelievers-are completely honest with others and ourselves, but atheists have removed one very common and profound source of personal inauthenticity.


. Freedom from fear of others beliefs. While we all have good reason to fear some acts motivated by religious beliefs, atheists need not fear exposure to others beliefs. Atheists dont believe that a change of their own beliefs will cause them to lose some eternal benefit or incur eternal damnation, and they have no creed or sacred book that discourages their association with those having different views on religion. They are free to associate with whomever they please, to read whatever interests-even challenges-them, and to subject their own views to questioning. These freedoms make full engagement in the world less threatening to atheists, and open its wonders to them.


. Freedom from fear of the hereafter. Many god-worshipers believe that there is an afterlife that can be wonderful or horrible, and that the nature of ones afterlife depends on believing and doing precisely the right things here. Many of those afterlife-believers know that there is disagreement among them as to which beliefs and acts confer the desired ticket. Accordingly, they should have at least a vague uneasiness about their own afterlife qualification status. And even among those who are certain they know and have satisfied the admissions formula, there must be dread for the fate of loved ones (atheists, agnostics, or those of other faiths) who arent meeting that formula, and great internal tension over conflicting drives to convert loved ones for their own good and to remain silent for the sake of the short-term earthly relationship. Atheists might feel the same tension between their own desires to convert and to converse with god-worshiping loved ones, but are freed from worry that anyone will suffer eternally on account of their beliefs.


4. Responsible citizenship. Religions divide people, and those divisions have caused and are causing incalculable suffering. Religious dogmas can cut off evaluation of the facts bearing on important matters of public policy such as population growth. An atheist is free to engage any persons, facts, or ideas, and can respond to them on the basis of their merits. The progress of mankind has depended, and will depend, on the extent to which people do that. -L Becker, lbecker@mn.astound.net


I believe there are five major reasons why people cling to religion


1. An afterlife, a soul, life eternal. This is perhaps the most powerful attraction. What thinking being really wants to contemplate a final end to their personality, their very essence? How many parents, confronted with the death of a child, are comforted by the belief that their son or daughter is not really dead, but simply in a different place, a nice place (heaven) perhaps watching them as they go about their daily affairs. How could you ask people to really give that dream up?


. A friend in high places. Imagine having an open and direct line to the ear of the creator of the universe, the most powerful leader and being anywhere, a being who not only listens to you but occasionally, grants your wishes. Wow! Its like having your own genie in a bottle. To give up praying to your powerful but imaginary friend is to give up your genie; its a very tough thing to do.


. A powerful force to administer justice to the evil. How could humanity keep its sanity if it felt that the Hitlers and Stalins and evil emperors of the world would not get their just punishments when they finally came before God. Judgment Day is one of the most popular and tenacious teachings of all religions.


4. Control. Religion comes with a lot of rules that control the population and help others to manipulate it. World leaders for example, routinely capitalize on religion to get their soldiers to fight to the death. The power that religion has on controlling mens actions has not been lost on world leaders. From medicine men to witch doctors to priests to kings, everything from rigid social conformity to abortion to the brutal conquest of the world by Christians following their manifest destiny has been controlled via religion.


5. Community. Church is a very attractive way to make and keep friends and feel a part of a community. Sometimes, that community does good things that give you a sense of warmth. Sometimes, it can even do horrible things to others, all in the name of religion. Even so, people cling to religion, in part, to belong!


Why then, with all these good reasons, have I abandoned religion?


A line from the book and movie Contact by Carl Sagan can best summarize my reason. In the story, Palmer Jost is explaining to Elle Arroway why he opposed her nomination to become the Earths ambassador to space. He stated that he could not in good conscience, vote for a person who thought that the 5 percent of the people on Earth who believe in God were suffering from some mass delusion. Her response was simple wishing for it does not make it so! What then? If it is not true, and you know it, what do you do? Do you knowingly delude yourself into trying to believe it anyway? In short, do you lie to yourself in exchange for some of those precious benefits?


I believe that deep down most people have answered that question with a yes. In short, they agree to be brainwashed! If a person, with help from preachers and books and friends and world leaders can actually fool him/herself into believing in souls and ghosts and eternal life and powerful Gods to watch over us, what have we got to lose?


I faced that question many years ago and realized what I had to lose was myself. We only have one time around on Earth. I would rather live that time being honest to myself, shaping my values based upon universal morality and truth, not some fear of the fires of hell or Gods who created us on a whim and play with us like toys. I would rather live a life of truth than a life deluding myself into a belief I know is false. -Frank Gregorio, fs.gregs@gte.net


We used to sing a song that said, I can tell you now the time and I can take you to the place where the Lord saved me by his wondrous grace. A large amount of time in our Pentecostal services was devoted to such testimonials by converts telling the story of how they had been saved, born again, passed from death to life, the before and after, and how they knew it had happened because they now loved the brethren (and sistern). As a Christian, these were joyous reinforcing bits of soul food-Joy unspeakable and full of glory. That many of us have had Pauline like, on-the-road-to-Damascus experiences when losing our religion is not celebrated often enough. Hearing such stories always bolsters me. Not all of our stories may be equally dramatic but most of us can hark back to some event where a wondrous doubt entered our consciousness. You can remember where and when it happened. You want to sing songs to the glory of that moment.


The defining moment in my life happened in a class in New Testament Greek at John Brown University, Siloam Springs, Arkansas in 14. We Preacher Boys had just returned to class from the compulsory weekly chapel service at the Cathedral of the Ozarks. It had been a glorious service. The guest speaker was a well-known radio preacher from the West Coast. He had preached on the meaning of Zionism for Born Again Christians-Israel had just become a nation! The bottom line to his exciting message was that now that Israel was a nation Jesus would return within the next 0 to 40 years. He proved all this by the Bible. You cannot imagine the joy that good news brought to we who were preparing to go out and preach the gospel of Jesus Second Coming. As we walked back to class, we were, as William James expressed it, When we lifted one foot it said GLORY! And when we lifted the other foot it said AMEN! Within our lifetime, Jesus would have returned and we Born Again would be ruling the world. It doesnt get any better than that.


The professor could hardly get us to settle down and have class. He finally said, Have any of you ever read a book entitled, I Have Been Robbed? Of course, none of us had. The book raised the question about the whole concept of a God who would have a chosen people whom He would bless and whose enemies he would curse. He did not talk more than five minutes but as he spoke a brilliant doubt began to flood my soul. We do not praise doubt nearly enough. If, I reasoned, the story of the chosen people is not true then none of it is true. All of it-the story of Adam and Eve, Noahs Flood, the Covenant with Abraham giving Canaan to the Israelis, the Cross making Christians now Gods chosen people, the awful events of the Second Coming, and the dreadful fear of hell-were removed from me as far as the east is from the west. I was set free at last. My lifes dreams of a large tent to preach the coming of Jesus washed ashore amidst rocks of doubt that eventually left me in a state of ecstasy. I have thoroughly enjoyed losing my religion. -Bob Minick, http//www.bobminick.com

FUNDAMENTALS OF INTERNET


.1 INTRODUCTION


The latest buzzword in computer world is 'Internet'. It has taken the entire world by surprise with its cutting edge technology to connect people and computers throughout the world. Using Internet, organizations all over the world can exchange data, people can communicate with each other in a faster and effective way, and researchers can gather information in their respective area of research. With help of video conferencing over Internet, it has become possible that people can even see each other while communicating and it is possible by video conferencing over Internet.Even one can do all his shopping sitting back at home. He does not bother to go to the crowded market place. Slowly shopkeepers are also opting for electronic commerce, which provides them greater reach and fastest way to do business over Internet. Don't get surprised, if you come to know that the Paanwalla in your locality has started selling his paan over Internet.


. OBJECTIVES


At the end of this lesson you would be able to


?define Internet


?understand and explain various terminology used in Internet


?use various services provided by Internet


?search for information over Internet


?enjoy Internet surfing


?send E-mail and do FTP


. INTERNET- THE HISTORY?


In 16, the U.S. Defence Department funded a project to develop a network, which can withstand the bombing. Basically the idea was to develop a very secure network which can work even after a nuclear attack. This project was known as ARPANET. The proposed network was not supposed to have a central controlwhich would be an obvious target. Ten years of research brought Local Area Ethernet Networks (LANs) and workstations were developed to get connected to LAN. These workstations and LANs were then connected to the ARPANET.For next decade the ARPANET grew and its decentralized features helped its rapid expansion. Computers connected to ARPANET used a standard or rule to communicate with each other. This standard used by ARPANET is known as NCP (National Control Protocol). Protocol is a network term used to indicate the standard used by a network for communication. But the passing time and rapid change in information technology suppressed NCP and brought TCP/IP (Transmission Control Protocol/Internet Protocol) in to the world of networking. TCP "converts messages into streams of packets at the source, and they are reassembled back into messages at the destination. IP handles the dispatch of these packets. It handles the addressing, and makes sure that a packet reaches its destination through multiple nodes and even across multiple networks with multiple standards. This flexibility of TCP/IP to handle multiple networks with multiple protocols encourages other networks to get connected to ARPANET. Slowly the ARPANET became a massive network of networks and now it is known as 'Internet'.


Internet is termed by some people as the world of largest democracy with no government. It has no state of head to control it.


Why do people want to get connected to Internet? May be because of freedom it provides. The Internet is a rare example of a large democracy with no state of head, no official censors, no bosses, no board of directors. Nobody controls the Internet and in principle, any computer can speak to any other computer, as long as it obeys the technical rules of the TCP/IP protocol.This freedom of Internet helped it to move out of its original base in military and research institutions, into elementary and high schools, colleges, public libraries, commercial sectors even into the shop of a vegetable vendor.


.4 SERVICES OF INTERNET - E-mail, FTP, Telnet, WWW


But what does one do with the Internet? May be four things, basically mail, discussion groups, long-distance computing, and file transfers. Internet mail is (e-mail or electronic mail), much faster as compared to normal postal mail. One can also send software and certain forms of compressed digital image as an attachment. News groups or discussion groups facilitate Internet user to join for various kinds of debate, discussion and new sharing. Long-distance computing was an original inspiration for development of ARPANET and does still provide a very useful service on Internet. Programmers can maintain accounts on distant, powerful computers, execute programs. File transfers service allows Internet users to access remote machines and retrieve programs, data or text.


(a) E-Mail (Electronic Mail)


E-mail or Electronic mail is a paperless method of sending messages, notes or letters from one person to another or even many people at the same time via the Internet. E-mail is very fast compared to the normal post. E-mail messages usually take only few seconds to arrive at their destination. One can send messages anytime of the day or night and it will get delivered immediately. You need not to wait for the post office to open and you don't have to get worried about holidays. It works 4 hours a day, seven days a week. What's more, the copy of the message you have sent will be available whenever you want to look at it - even in the middle of the night. You have the privilege of sending something extra even such as a file, graphics, images etc. along with your e-mail. The biggest advantage to using e-mail is that it is cheap, especially when sending messages to other states or countries and at the same time it can be delivered to a number of people around the world.


Although e-mail is faster and cheaper, it has many of the components of regular mail. It allows you to compose note, get the address of the recipient and send it. Once the mail is received and read, it can be forwarded, replied. One can even store it for later use, or delete.In e-mail even the sender can request for delivery receipt and read receipt from the recipient.


(i) Features of E-mail


?One-to-one or one-to-many communications


?Instant communications


?Physical presence of recipient is not required


?Most inexpensive mail service, 4-hours a day and seven days a week


?Encourages informal communication


(ii) Components of anE-mail Address


As in the case of normal mail system, e-mail is also based upon the concept of a recipient address. The email address provides all of the information required to get a message to the recipient from anywhere in the world. Consider the e-mail ID


john@hotmail.com


In the example above, "john" is the local part, which is the name of a mailbox on the destination computer, where finally the mail will be delivered. Hotmail is the mailserver where the mailbox "john" exists, .com is the type of organisation on net, which is hosting the mail server.


There are six main categories;


comCommercial institutions or organization


edu Educational institutions


gov Government site


milMilitary site


net Gateways and administrative hosts


org Private organizations


(b) FTP (File Transfer Protocol)


File Transfer Protocol, is anInternet utility software used to upload and download files. It gives access to directories or folders on remote computers and allows software, data and text files to be transferred between different kinds of computers. FTP works on the basis of same principle as that of Client/Server. FTP "Client" is a program running on the your computer that enables you to talk to, and get stuff from, remote computers. The FTP client takes FTP commands and sends them as requests for information from the remote computer or known as FTP servers. To access remote FTP server it is required but not necessary to have an account in the FTP server. When the FTP client gets connected, FTP server asks for the identification in-terms of User Login name and password of the FTP client.If one does not have an account in the remote FTP server, still he can connect to the server using anonymous login.


Using anonymous login anyone can login in to a FTP server and can access public file archives, anywhere in the world, without having an account. One can easily Login to the FTP site with the username anonymous and e-mail address as password.


The basic objectives of FTP are


?to give flexibility and promote sharing of computer programs, files and data


?to transfer data reliably and more efficiently over network


? to encourage implicit or indirect use of remote computers using Internet


? to shield a user from variations in file storage systems among hosts.


Fig. .1


The basic steps in an FTP session are


?Start up your FTP client; by typing ftp on your system's command line/'C' prompt (or, if you are in a Windows, double-click on the FTP icon).


?Give the FTP client an address to connect to. This is the FTP server address to which the FTP client will get connected


?Identify yourself to the FTP remote site by giving the Login Name


?Give the remote site a password


?Remote site will verify the Login Name/Password to allow the FTP client to access its files


?Look directory for files in FTP server


?Change Directories if required


?Set the transfer mode (optional);


?Get the file(s) you want; and


?Quit.


(c) Telnet (Remote Computing)


Telnet or remote computing is telecommunication utility software, which uses available telecommunication facility and allows you to become a user on a remote computer. Once you gain access to the remote computer, you can use it for the intended purpose. The TELNET works in a very step by step procedure. The commands typed on the client computer are sent to the local Internet Service Provider (ISP), and then from the ISP to the remote computer that you have gained access. Most of the ISP provides facility to TELNET into your own account from another city and check your e-mail while you are travelling or away on business.


The followings steps are required for a TELNET session


?Start up the TELNET program;


?Give the TELNET program an address to connect to (some really nifty TELNET packages allow you to combine steps 1 andinto one simple step!);


?Make a note of what the "escape character" is;


?Log in to the remote computer;


?Set the "terminal emulation;"


?Play around on the remote computer; and


?Quit.

.5 WORLD WIDE WEB (WWW)


WWW is the acronym for the World Wide Web.It is also commonly known as 'The Web'. The WWW is hypertext based information retrieval tool. One can easily surf the Web by jumping from one document to another using the links in those documents. These documents can be in many formats, such as text, graphics, animation, sound and latest is video. They may also be a combination of all these. All the information on Internet are presented to the user as a document or more popularly known as Web Page. All these Web Pages are link to each other or even to section within a Web Page. And these links are known as Hyper Links.


The tool used to view these Web Pages on Internet is known as Internet browser or simply browser. It is a software program specifically developed to extract information on user request from the Internet and present them as a Web Page to the viewer. There are several browsers available in the market. However the most popular are Internet Explorer from Microsoft and Netscape from Netscape Inc. The process of using browser to view information on Internet is known as Browsing or Surfing.


Fig. .


(a) Internet Address


Just like every house, every office, every location has an address, every page on the Internet has a unique address. This address is used get the web page for user from Internet.


Just as the address of a house or office is known as its postal address, the address on the Internet is known as URL (Uniform Resource Locator). A typical Internet address or URL would look like;


http//www.nos.org/computers/internet/url.htm


The URL locates a particular web Page, among all the computers connected to the Internet. The URL contains the components that specify the protocol, server, and pathname of an item. Let us examine the URL given above (http//www.nos.org/computers/internet/url.htm).


The protocol is followed by a colon (http), the server is preceded by two slashes (//www.nos.org), and each segment of the pathname is preceded by a single slash (/computers/internet/url.htm). A protocol is set of rules that tells the computer know how to interpret the information at that address.


Fig. .


The first component, the protocol, defines the manner for interpreting computer information. Many Internet pages use HTTP (HyperText Transfer Protocol). Other common Internet protocols that one might come across are FTP (File Transfer Protocol), NEWS (Usenet news groups protocol), and GOPHER (an alternative transfer protocol). Gopher protocol is mostly out of date now.


The second component, the server (www.nos.edu), identifies the computer system that stores the information you seek and is always preceded by two slashes. A server is a computer that has information stored on it and sends it to the client, when a request is made. Each server on the Internet has a unique address name whose text refers to the organization maintaining the server.


The last component (/computers/internet/), defines the path within the Server where the requested item (url.htm) will be found. Most of the Web pages will have .htm or .html as their secondary or extension name.


(b) How to get connected to Internet


There are various type of connectivity to get hook on to Internet. They all can be broadly classified into following category.


(i) Gateway Access


Gateway Access is also known as Level-One connection. It is the access to the Internet from a network, which is not on the Internet. The gateway allows the two different types of networks to "talk" to each other. But the users of the Gateway Internet have limited access to the Internet. They might not be able to use all the tools available on Internet. The local Internet Service Provider (ISP) normally defines this limitation.


Good example of network with Level One connectivity within India is that of VSNL (Videsh Sanchar Nigam Limited). All access to Internet from India are through VSNL gateway.


Fig. .4


(ii)Dial-up Connection


'Dial-up' connection is also known as Level Two connection. This provides connection to Internet through a dial-up terminal connection. The computer, which provides Internet access is known as'Host' and the computer that receives the access, is'Client' or 'Terminal'. The client computer uses modem to access a "host" and acts as if it is a terminal directly connected to that host. So this type of connection is also known as 'Remote Modem Access' connection. And the host to which the client gets connected is actually connected to the Internet by a full time connection (See Leased Connection).

In dial-up connection to Internet, Host carries all the command that are typed on a client machine and forward them to Internet. It also receives the data or information from the Internet on behalf of the 'Client' and passes it to them. The client computer acts as a 'dumb' terminal connected to remote host.


This type of connection can further be divided into two categories.


(iii)Shell Connection


In this type of Internet Connection, the user will get only textual matter of a Web Page. This connection does not support Graphics display. However the user will be able to surf the Internet, do FTP, receive mail. Shell Accounts were the only type of Internet access available for many years before the Internet entered in to the world of graphics and became more users friendly.


(iv) TCP/IP Connection


Today's graphical World Wide Web browsers provide easier access with multimedia sound and pictures. The major difference between Shell and TCP/IP account is that, Shell account can only display text and does not support graphics display, whereas TCP/IP can display both. Hence it is more popular Internet connection. Shell accounts are slowly phasing out from the Internet scenario.


To access any of these dial-up accounts you need the followings;


?Computer


?Modem


?Telephone Connection


?Shell or TCP/IP account from the ISP


?Internet client software such as Internet browser.


(v) Leased Connection


Leased connection is also known as direct Internet access or Level Three connection. It is the secure, dedicated and most expensive, level of Internet connection. With leased connection, your computer is dedicatedly and directly connected to the Internet using high-speed transmission lines. It is on-line twenty-four hours a day, seven days a week. Leased Internet connections are limited to large corporations and universities who could afford the cost.

PUBLISHING ON THE WEB AN INTRODUCTION


4.1 INTRODUCTION


In the previous lesson we had discussed about the concept of World Wide Web (WWW). Web page design is exciting and can provide an interesting challenge for any body. In this lesson we will introduce you to the concept of web page designing. You will come to know that with its rapid growth, Internet or web has given access to more and more users. However each and every user accesses or uses the web in a different way than the other. As per statistics, more women and children are using the web and in different ways than the male users. The development of web page is for a specific audience. Hence, it is essential for a web designer to know who the audience are. For example if you teach high school mathematics, your primary audience is your class and secondary audience are other students, colleagues, parents, and your local community.


With Internet and web pages both the organisation and the individual involved will gain mileage.For an organisation, this would provide i) a low cost information distribution system, ii) make database available for others to use, and maintain the security, iii) collect information provided by others on Internet to expand and improve service to a target audience, and iv) provide low-cost training. On the other hand for an individual it would mean i) get acquainted with new technology, ii) learn new skills, iii) receive low cost training and other information, and iv) get connected with other web creators with ease.


4. OBJECTIVES


After going through this lesson you should be in a position to


?explain the concepts of the Internet and web publishing


?access Internet


?design web pages


?work with HTML


4. WEB PUBLISHING


When you browse the Internet you will come across quite often the word home page. Home page is the entry or starting point of a website. It is more or less in the format of the contents of a book or magazine. In other words it is the welcome page of the website you are visiting, which in most cases gives an overview of what the website contains. One should not be surprised to see only one page in a website. Website can have one or more than one page, or a few long ones, depending on it's design. But normally the website contains more than one page. Web pages vary in their look and content, but most of them follow a traditional book or magazine format. At the top of the page resides the master head or heading or banner graphic giving the main theme of the page. Then there is a list of items, such as subjects, with a brief description. The items listed are either hot or cold. When we say they are hot, it means they are linked to other pages within the same website or to other websites. These links are highlighted words in the body of the text, or in a list, or they can even be the images that link to other content. But how you will know the text is hot or cold. Usually the hot text appears in different colour from the rest of the textusually in blue and underlined. When one moves the cursor over this text or graphics link, it will change from an arrow to a hand shape. And when you click on the hot text or image, you will be taken to the linked web page or website. Once you come back to a page with a link you have already visited, the hot text or hypertext words will appear in a different colour other than blue, so you know you have already visited there. But that does not prevent you from visiting the link again and again, you can certainly go there as many times, as you like. As the information and links are not static, don't feel surprised if the page looks different and the information has changed, when you visit a site, next time. The Internet is a dynamic medium of communication for displaying information. To encourage visitors to return to a site, it is very much required to change the look and feel of the web pages from time to time.


(a) Planning Cycle


Web planning involves a structured approach involving conceptualization of design and organizing the web developer and information resources required making the designing a reality. If the design is for a large and complex site, it is always advisable to note down all the planning, preferably in a notebook. This note book can be used as a guide to deliver all the raw material needed for web designing such as HTML, Java scripts, graphics, text, animation and icons, etc. You should also get ready with the policies and guidelines to be followed for developmental activities to give the web sites a professional touch.


This requires careful planning. Create the sketch of the site, before the actual development work takes place. This will help to reduce the re-work while development is on. Basically this will act as a site roadmap to be followed by the web designer to create the actual web sites. The most critical part a web page is its content. While working on content for a web page, it is necessary to take the target audience into consideration. Collect all the materials such as brochure, contact information, review, lessons, teaching material, quiz, FAQ's, photographs etc.It is not necessary to use all of them in one go, but they will be handy when something needs to be changed.


Once the conceptualization, collection of materials and creation of roadmap of the site is ready, it is time to decide how you are going to publish your site or how the web users will come to know about your site. Take the help of promotional Internet sites, professional organizations etc.


(b) Design Cycle


Now let us look how user designs the web page from an information design perspective pointed view and not from a graphics design.Web page contents should not have more graphic page. In fact, the basic idea about a web page is information sharing enhanced by other elements such as graphics, animation, etc.


(c) Design Basics


Following are some basic steps to be followed while creating web pages.


?Create a Welcom/Index/first page of your web site.


?Avoid use of heavy graphics in the first page from the user's point of view.


?Page should be descriptive and interactive both as per requirements.


Some minimum technical requirements might include


?Fast loading of pages


?Presentation with clarity and readability - with or without graphics


?Validation of the contents


?Easy and clear navigation


?Instruction on how to use the site.


Identify and address all potential problems such as


?Slow connections


?Physical constraints of the user such assight or hearing impaired visitors


?Platform support


?Browser support etc.


4.4HTML (HYPERTEXT MARKUP LANGUAGE)


So far we have discussed the points you should be careful about while designing a web page. But what language we should use for creating web pages? HTML or HyperText Markup Language is used for creating web pages. Although HTML stands for HyperText Markup Language, it is not a programming language like Java. The basic function of the HTML is to describe the standard () how a browser should display text and multimedia elements such as graphics, animation, etc. It works on a limited number of tags and is not difficult to learn and use. Let us learn how it works.


How HTML works


?The HTML is platform independent that is computer and computer operating system on which it is running.It means that HTML uses a small number of tags to create Web page. Any Web server regardless of their location and operating system can publish these web pages. These web pages can also be viewed or displayed by any Web browser regardless of the platform on which it is running.


?As we have discussed, HTML works on tags. These HTML tags control the page structure and the style sheet controls the details about page layout and their presentation. In other words, HTML style sheet provides consistency and creativity to create professional quality web pages.


?The basic structure of using tag istag_name some text /tag_name. For example, the tag for making text bold is b this is bold /b.And when displayed in a browser it will be displayed, as this is bold.


?Web page is made up of two sections head and body. Each of these sections is enclosed within a pair of html tags. The head section describes the page content while the body section defines the web page look and feel. Most of HTML tags are used in the body section, whereas the number of tags is limited in the head section. The standard web page structure in HTML is


html


head


titleTitle of the page is given here/title


/head


body


web page contents goes here


/body


/html


IN-TEXT QUESTION 4.1


1.State whether the following statements are True or False


(a) Hyper Text Makeup Language is used for creating web pages.


(b) The HTML is platform independent.


(c)HyperText Markup Language is a programming language like Java.


(d) All web page starts with a welcome page.


(e) Web page is made up of two sections head and body.


(f) Use of heavy graphics will lead to slow loading of pages.


(g) Web pages can not be descriptive and interactive.


4.5 GETTING STARTED WITH HTML


Before you actually start using HTML, you need certain things such as


(a) Text Editor


To create an HTML document, a text editor is required. Any text editor, which can save the file in plain ASCII format, is good enough for creating HTML file. You can use right from MS-DOS editor "EDIT" to Microsoft Word for creating HTML document.


(b) Web Browser


After creating an HTML document, it is required to be viewed in a browser to see how it looks.There are several browsers available for viewing HTML documents such as Netscape Navigator, NCSA Mosaic, Microsoft Internet Explorer, WebExplorer etc. But most popular among them are Microsoft Internet Explorer and Netscape Navigator. However, it is advisable to use at leasttwo browsers to experimentwith the look and feel of the developed web pages.


(c) Graphics Tool


Internet supports only GIF (Graphics File Format). Any other graphics file such as BMP, PCX,etc needs to be converted in GIF format to be used in Internet. So you must use graphics software that are capable of creating GIF graphics file. There are a number of graphics packages available such as Adobe PhotoShop, Adobe Illustrator, etc, which support GIF file.


(d) Content


The actual contents of a web page are - all of the words, images, and links, which a web user can read and interact with. So all your content should be well documented and well researched before they are put in the web page. All graphics, Icons, etc. should be of correct impact.


(e) Hyperlink


Hyperlink is used to link between pages. A well-designed web page should have proper and meaningful links to other documents or web pages. The hyperlink can be a highlighted text in the document or images in the document.


4.6 USING HTML TAGS


The HTML document uses HTML tags, be it in the beginning of the document or end of it. These tags tell a Web browser where the HTML in the document begins and ends. The HTML document starts with a tag called HTML and ends with a tag /HTML. i.e.


HTML


HTML


/HTML


The first tag HTML indicates the beginning of the HTML document and the last tag /HTML indicates the end of the document. Within these two resides the body of the HTML which defines the look and feel of the web page.


All the HTML tags end with the same tag name, but with a prefix of '/' with the tag name such as /HTML.


(a) Head


The second tag in the HTML document is HEAD. This tag contains all header information about the document such as document title, author name, etc.It ends with /HEAD.


(b)Title


This appears within the Head tag structure. This is where the title of the web page should be given, which will appear at the top of the browser's title bar, and also in the history list. The title of the document should be logically related to the content of the web page, and must be short but informative enough about the web page. As a norm, there should only be one title per document.


(c) Body


The actual works lies in the Body of the document. This appears after the Head tags. Between the Body tags, remains all the stuff that gets displayed in the browser window like all of the text,graphics, and links.


(d) Headings


As we know, the entire HTML document contains information that appears in different parts or section titles.


There are a total of six levels of headings, from Heading 1 through Heading 6. They are marked as H1 for heading one and H6 for heading six. Heading 1 (H1) is "most important" and Heading 6 (H6) is "least important" in an HTML document.Given beloware the structure of all six heading tags


H1Heading 1/H1


HHeading /H


HHeading /H


H4Heading 4/H4


H5Heading 5/H5


H6Heading 6/H6


A heading in an HTML document always begins at the margin of a line. It also forces a line break at the end of the heading. In other words, there cannot be two headings on the same line.


(e) Paragraphs


Paragraphs are treated as the most basic structures in HTML. Presetting information in paragraphs is quite common in Web pages.Paragraph tags are P for beginning of the paragraph and /P for the end.In other words in HTML creation, the beginning of a paragraph is marked by P, and the end by /P.


(f)Lists


As the name suggests, lists is the index of items to be appeared in a web page in a specific format. There are three types of lists, namely Unordered, Ordered and Definition lists. Out of these three most widely used lists are un-ordered and Ordered list. Let us discuss them one by one.


(i)Unordered lists


While reading Microsoft Word you have known the 'Bullet List'. It is a list of items, where each listed item is preceded by a 'bullet' (a small black circle).In HTML, this bulleted list is termed as 'Unordered list'.


Unordered list starts with a tag UL and ends with a tags /UL. Now all the items to be listed start with an HTML tag LI, which stands for "List Item." LI has a corresponding closing tag /LI, but this closing tag is not compulsory to be given.There is no limitation to the number of list of items. Here is an example of Unordered List of items;


UL


LIWindows5


LIMS-DOS


LIGraphics


LIAnimation


LIInternet


/UL


And the result will be


?Windows5


?MS-DOS


?Graphics


?Animation


?Internet


Almost anything can be put into a list itemline breaks, entire paragraphs, images, links, or even other lists.


(ii) Ordered lists


In HTML, both unordered and ordered list looks similar and same set of rules applies to both of them. However, the differences between both of them is that instead of using UL and /UL, an ordered list is contained within the tags OL and /OL and the list items are preceded by numbers such as 1,, and so on instead of a 'Bullet'. However, when an ordered list is displayed in a Web browser, it uses an automatically generated sequence of items.


Here is an example of Ordered List of items;


OL


LIWindows5


LIMS-DOS


LIGraphics


LIAnimation


LIInternet


/OL


And the result will be


1.Windows5


.MS-DOS


.Graphics


4.Animation


5.Internet


As in the case of unordered list, almost anything can be put into a list itemline break, entire paragraphs, images, links, or even other lists. They can also be nested as unordered lists. Unordered lists can be nested in ordered lists, vice versa. For example;


UL


LIRakesh


LIHarish


LIManoj


LISwati


LIReena


OL


LI1 yrs.


LI0 yrs.


LI5 yrs.


LI1 yrs.


LI0 yrs.


/OL


/UL


This will result in


?Rakesh


?Harish


?Manoj


?Swati


?Reena


1.1 yrs.


.0 yrs.


.5 yrs.


4.1 yrs.


5.0 yrs.


4.7 CHARACTER STYLE TAGS


In addition to the above there can also be character style tags used for bold, italics, underline etc.They are sometimes called forced style tags, because their very nature forces a certain style on the character. The three most commonly used character style tags are


(a) Boldface


This tag is used to make characters boldface. The tags used are B and /B. And everything between B and /B is boldfaced. For example,


B This is a Web Page/B will result in This is a Web Page.


(b) Italics


HTML tags I and /I are used to put the characters in Italics. Everything between I and /I is italicized. For example,


I This is a Web Page/I will result in This is a Web Page.


(c) Underline


As the name suggests, the Underline tags U and /U are used to put character in underlined format. That means everything between U and /U should be underlined. For example,


U This is a Web Page/U will result in This is a Web Page.


4.8 THE HTML ANCHOR OR LINKS


As we have already discussed, a well-designed web page will have links to other pages and even to the outside world. These links can be a word within the text or an image in the document and they can appear anywhere in the HTML document. The links in HTML document starts with a tag A and ends with /A. However, the A tags are not used alone, but this will contain attribute like HREF.. HREF


HREF stands for "Hypertext REFerence", which indicates the location of the file to be linked to current page. The links are in the form of A HREF="URL or the address of the file", where URL is the location of the resource to which the file to be linked. For example, the National Open School Web server is at "http//www.nos.edu/". A sentence, which contained a link to that address, would look something like below


For further information, please check out the A HREF="http//www.nos.edu/"National Open School Web server/A.


The words between A and /A the open and close of the anchor ("National open School Web server") will be displayed as a hyperlink. Here is how it will look like National Open School Web server! Clicking that link from a Web browser will load the National Open School Web server's main or index page.


(a) IMG


Till now we have discussed how to create and format text in an HTML document. Image also plays an important role in Web page creation. Images are inserted in Web documents using the IMG tag IMG and this tag has no closing tag such as /IMG. However an IMG tag requires the location of the images file that is supposed to be placed in the document. This does not essentially mean that the said image file will be included in the HTML file. Visually, images are part of a Web page, but in reality an HTML file and any graphics it refers to are all separate files. All the referred graphics files are stored as individual files in the web server and they don't have to be in the same directory as the HTML document. But it is a good practice to put all the graphics files in a separate folder or directory preferably by images directory for easy location and manipulation.


But IMG tags alone does not help to place images in the HTML document. For IMG tags to work, you need another attribute called 'SRC'. This attribute, which stands for 'source' or 'source of this graphics' points to location of the graphics file. The source can either be a URL giving path for outside server or a path in the same server where the graphics file is stored. When this attribute is used along with IMG tags, a typical image tag will look like;


IMG SRC="URL/ path of graphic file"


In other words, if there is a graphics file called 'welcome.gif' in NOS web server's graphics folder than the above image tags will look like


IMG SRC=" htttp//www.nos.edu/graphics/welcome.gif"


The browser will put the graphic 'welcome.gif' wherever an image tag occurs in the document. Browser will treat this as another piece of text.


Images can be placed almost anywhere within the body of the document, they can be between words, paragraphs, within paragraphs, in list items or even a link.

THE CONCEPT OF MULTIMEDIA


5.1 INTRODUCTION


As the name suggests, multimedia is a set of more than one media element used to produce a concrete and more structured way of communication. In other words multimedia is simultaneous use of data from different sources. These sources in multimedia are known as media elements.With growing and very fast changing information technology, Multimedia has become a crucial part of computer world. Its importance has realised in almost all walks of life, may it be education, cinema, advertising, fashion and what not.


Throughout the 160s, 170s and 180s, computers have been restricted to dealing with two main types of data - words and numbers. But the cutting edge of information technology introduced faster system capable of handling graphics, audio, animation and video. And the entire world was taken aback by the power of multimedia.


5. OBJECTIVES


After going through this lesson you should be able to


?explain what is multimedia


?understand the importance of individual media elements


?identify different hardware components required to run a multimedia


?appreciate the impact of audio in educational presentation


?describe how visual images, graphics and audio can be added to a presentation


?enhance the capability of multimedia through interactive video impact


5. WHAT IS MULTIMEDIA?


Multimedia is nothing but the processing and presentation of information in a more structured and understandable manner using more than one media such as text, graphics, animation, audio and video. Thus multimedia products can be an academic presentation, game or corporate presentation, information kiosk, fashion-designing etc. Multimedia systems are those computer platforms and software tools that support the interactive uses of text, graphics, animation, audio, or motion video. In other words, a computer capable of handling text, graphics, audio, animation and video is called multimedia computer. If the sequence and timing of these media elements can be controlled by the user, then one can name it as Interactive Multimedia.


5.4DIFFERENT MEDIA ELEMENTS


(i) Text


Inclusion of textual information in multimedia is the basic step towards development of multimedia software.Text can be of any type, may be a word, a single line, or a paragraph. The textual data for multimedia can be developed using any text editor. However to give special effects, one needs graphics software which supports this kind of job. Even one can use any of the most popular word processing software to create textual data for inclusion in multimedia. The text can have different type, size, color and style to suit the professional requirement of the multimedia software.


(ii) Graphics


Another interesting element in multimedia is graphics. As a matter of fact, taking into consideration the human nature, a subject is more explained with some sort of pictorial/graphical representation, rather than as a large chunk of text. This also helps to develop a clean multimedia screen, whereas use of large amount of text in a screen make it dull in presentation.


Unlike text, which uses a universal ASCII format, graphics does not have a single agreed format. They have different format to suit different requirement. Most commonly used format for graphics is .BMP or bitmap pictures. The size of a graphics depends on the resolution it is using. A computer image uses pixel or dots on the screen to form itself. And these dots or pixel, when combined with number of colors and other aspects are called resolution. Resolution of an image or graphics is basically the pixel density and number of colors it uses. And the size of the image depends on its resolution.A standard VGA (Virtual Graphics Arrays) screen can display a screen resolution of 640 ? 480 = 0700 pixel. And a Super VGA screen can display up-to 104 ? 768 = 7864 pixel on the screen.While developing multimedia graphics one should always keep in mind the image resolution and number of colors to be used, as this has a direct relation with the image size. If the image size is bigger, it takes more time to load and also requires higher memory for processing and larger disk-space for storage.


However,different graphics formats are available which take less space andare faster to load into the memory.


There are several graphics packages available to develop excellent images and also to compress them so that they take lesser disk-space but use higher resolution and more colours. Packages like Adobe PhotoShop, Adobe Illustrator, PaintShop Pro etc. are excellent graphics packages. There are Graphics gallery available in CD's (Compact Disk) with readymade images to suit almost every requirement. These images can directly be incorporated into multimedia development.


(iii) Animation


Moving images have an overpowering effect on the human peripheral vision. Followings are few points for its popularity.


Showing continuity in transitions


Animation is a set of static state, related to each other with transition. When something has two or more states, then changes between states will be much easier for users to understand if the transitions are animated instead of being instantaneous. An animated transition allows the user to track the mapping between different subparts through the perceptual system instead of having to involve the cognitive system to deduce the mappings.


Indicating dimensionality in transitions


Sometimes opposite animated transitions can be used to indicate movement back and forth along some navigational dimension.One example used in several user interfaces is the use of zooming to indicate that a new object is "grown" from a previous one (e.g., a detailed view or property list opened by clicking on an icon) or that an object is closed or minimized to a smaller representation. Zooming out from the small object to the enlargement is a navigational dimension and zooming in again as the enlargement is closed down is the opposite direction along that dimension.


Illustrating change over time


Since animation is a time-varying display, it provides a one-to-one mapping to phenomena that change over time. For example, deforestation of the rain forest can be illustrated by showing a map with an animation of the covered area changing over time.


Multiplexing the display


Animation can be used to show multiple information objects in the same space. A typical example is client-side imagemaps with explanations that pop up as the user moves the cursor over the various hypertext anchors.


Enriching graphical representations


Some types of information are easier to visualize with movement than with still pictures. Consider, for example, how to visualize the tool used to remove pixels in a graphics application.


Visualizing three-dimensional structures


As you know the computer screen is two-dimensional. Hence users can never get a full understanding of a three-dimensional structure by a single illustration, no matter how well designed. Animation can be used to emphasize the three-dimensional nature of objects and make it easier for users to visualize their spatial structure. The animation need not necessarily spin the object in a full circle - just slowly turning it back and forth a little will often be sufficient. The movement should be slow to allow the user to focus on the structure of the object.


You can also move three-dimensional objects, but often it is better if you determine in advance how best to animate a movement that provides optimal understanding of the object. This pre-determined animation can then be activated by simply placing the cursor over the object. On the other hand, user-controlled movements requires the user to understand how to manipulate the object (which is inherently difficult with a two-dimensional control device like the mouse used with most computers - to be honest, D is never going to make it big time in user interfaces until we get a true D control device).


Attracting attention


Finally, there are a few cases where the ability of animation to dominate the user's visual awareness can be turned to an advantage in the interface. If the goal is to draw the user's attention to a single element out of several or to alert the user to updated information then an animated headline will do the trick. Animated text should be drawn by a one-time animation (e.g., text sliding in from the right, growing from the first character, or smoothly becoming larger) and never by a continuous animation since moving text is more difficult to read than static text. The user should be drawn to the new text by the initial animation and then left in peace to read the text without further distraction.


One of the excellent software available to create animation is Animator Pro. This provides tools to create impressive animation for multimedia development.


Video


Beside animation there is one more media element, which is known as video. With latest technology it is possible to include video impact on clips of any type into any multimedia creation, be it corporate presentation, fashion design, entertainment games, etc.


The video clips may contain some dialogues or sound effects and moving pictures. These video clips can be combined with the audio, text and graphics for multimedia presentation. Incorporation of video in a multimedia package is more important and complicated than other media elements. One can procure video clips from various sources such as existing video films or even can go for an outdoor video shooting.


All the video available are in analog format. To make it usable by computer, the video clips are needed to be converted into computer understandable format, i.e., digital format. Both combinations of software and hardware make it possible to convert the analog video clips into digital format. This alone does not help, as the digitised video clips take lots of hard disk space to store, depending on the frame rate used for digitisation. The computer reads a particular video clip as a series of still pictures called frames. Thus video clip is made of a series of separate frames where each frame is slightly different from the previous one. The computer reads each frame as a bitmap image. Generally there are 15 to 5 frames per second so that the movement is smooth. If we take less frames than this, the movement of the images will not be smooth.


To cut down the space there are several modern technologies in windows environment. Essentially these technologies compress the video image so that lesser space is required.


However, latest video compression software makes it possible to compress the digitised video clips to its maximum. In the process, ittakes lesser storage space. One more advantage of using digital video is, the quality of video will not deteriorate from copy to copy as the digital video signal is made up of digital code and not electrical signal. Caution should be taken while digitizing the video from analog source to avoid frame droppings and distortion. A good quality video source should be used for digitization.


Currently, video is good for


lpromoting television shows, films, or other non-computer media that traditionally have used trailers in their advertising.


lgiving users an impression of a speaker's personality.


lshowing things that move. For example a clip from a motion picture. Product demos of physical products are also well suited for video.


Audio


Audio has a greater role to play in multimedia development. It gives life to the static state of multimedia. Incorporation of audio is one of the most important features of multimedia, which enhance the multimedia usability to its full potential. There are several types of sound, which can be used in multimedia. They are human voices, instrumental notes,natural sound and many more.All these can be used in any combination as long as they give some meaning to their inclusion in multimedia.


There are many ways in which these sounds can be incorporated into the computer.For example;


lUsing microphone, human voice can directly be recorded in a computer.


lPre-recorded cassettes can be used to record the sound into computer.


lInstrumental sound can also be played directly from a musical instrument for recording into the computer.


The sound transmitted from these sources is of analog nature. To enable the computer to process this sound, they need to be digitised.


As all of us know that sound is a repeated pattern of pressure in the air and a microphone converts a sound wave into an electrical wave. The clarity of sound, the final output depends entirely on the shape and frequency of the sound wave. When digitised (recording into computer), the error in sound can be drastically reduced.Audio need to be converted into digital format to produce digitised audio in order to use them in multimedia. And these digitised sounds again can be re-converted into analog form so that the user can hear them though the speakers.


Musical Instrument Digitisation Interface or MIDI provides a protocol or a set of rules, using which the details of a musical note from an instrument is communicated to the computer. But MIDI data is not digitized sound. It is directly recorded into the computer frommusical instruments, whereas digitised audio is created from the analog sound. The quality of MIDI data depends upon the quality of musical instrument and the sound system. A MIDI file is basically a list command to produce the sound. For example, pressing of a guitar key can be represented as a computer command. When the MIDI device processes this command, the result will be the sound from the guitar. MIDI files occupy lesser space as compared to the digitised audio and they are editable also.


The main benefit of audio is that it provides an exclusive channel that is separate from that of the display. Speech can be used to offer commentary or help without obscuring information on the screen. Audio can also be used to provide a sense of place or mood. Mood-setting audio should employ very quiet background sounds in order not to compete with the main information for the user's attention. Music is probably the most obvious use of sound. Whenever you need to inform the user about a certain work of music, it makes much more sense to simply play it than to show the notes or to try to describe it in words.

5.4MULTIMEDIA HARDWARE REQUIREMENTS


For producing multimedia you need hardware, software and creativity. In this section we will discuss the multimedia equipment required in a personal computer (PC) so that multimedia can be produced.


(a) Central Processing Unit


As you know, Central Processing Unit (CPU) is an essential part in any computer. It is considered as the brain of computer, where processing and synchronization of all activities takes place. The efficiency of a computer is judged by the speed of the CPU inprocessing of data. For a multimedia computer a Pentium processor is preferred because of higher efficiency. However, the CPU of multimedia computer should be at least 486 with math coprocessor. The Pentium processor is one step up the evolutionary chain from the 486 series processor and Pentium Pro is one step above the Pentium. And the speed of the processor is measured in megahertz. It defines the number of commands the computer can perform in a second. The faster the speed, the faster the CPU and the faster the computer will be able to perform. As the multimedia involves more than one medial element, including high-resolution graphics, high quality motion video, and one need a faster processor for better performance.


In today's scenario, a Pentium processor with MMX technology and a speed of 166 to 00 MHz (Megahertz) is an ideal processor for multimedia. In addition to the processor one will need a minimum 16 MB RAM to run WINDOWS to edit large images or video clips. But aor 64 MB RAM enhances the capacity of multimedia computer.


(b) Monitor


As you know that monitor is used to see the computer output. Generally, it displays 5 rows and 80 columns of text. The text or graphics in a monitor is created as a result of an arrangement of tiny dots, called pixels. Resolution is the amount of details the monitor can render. Resolution is defined in terms of horizontal and vertical pixel (picture elements) displayed on the screen. The greater the number of pixels, better visualization of the image.


Like any other computer device, monitor requires a source of input. The signals that monitor gets from the processor are routed through a graphics card. But there are computers available where this card is in-built into the motherboard. This card is also called the graphics adapter or display adapter. This card controls the individual pixels or tiny points on a screen that make up image. There are several types of display adapter available. But the most popular one is Super Virtual Graphics Arrays (SVGA) card and it suits the multimedia requirement. The advantage of having a SVGA card is that the quality of graphics and pictures is better.


Now the PCs, which are coming to the market, are fitted with SVGA graphics card. That allows images of up to 104 ? 768 pixels to be displayed in up to 16 millions of colours. What determines the maximum resolution and color depth is the amount of memory on the display adapters. Often you can select the amount of memory required such as 51KB, 1MB, MB, 4MB, etc. However, standard multimedia requirement is a MB of display memory (or Video RAM). But one must keep in mind that this increases the speed of the computer, also it allows displaying more colours and more resolutions. One can easily calculate the minimum amount of memory required for display adapter as


(Max. Horizontal Resolution x Max. Vertical Resolution ? Colour Depths. in Bits )/81 = The minimum video (or display) memory required in KB.


For example, if SVGA resolution (800?600) with 65,56 colours (with colour depth of 16) you will need


= 7.5 KB, i.e., approximately 1 MB of display memory.


Another consideration should be the refresh rate, i.e., the number of times the images is painted on the screen per second. More the refresh rate, better the image formation. Often a minimum of 70-7Mhz is used to reduce eye fatigue. As a matter of fact higher resolution requires higher refresh rates to prevent screen flickers.


(c) Video Grabbing Card


As we have already discussed, we need to convert the analog video signal to digital signal for processing in a computer. Normal computer will not be able to do it alone. It requires special equipment called video grabbing card and software to this conversion process. This card translates the analog signal it receives from conventional sources such as a VCR or a video camera, and converts them into digital format. The software available with it will capture this digital signal and store them into computer file. It also helps to compress the digitized video so that it takes lesser disk space as compared to a non-compressed digitized video.


This card is fitted into a free slot on the motherboard inside the computer and gets connected to an outside source such as TV, VCR or a video camera with the help of a cable. This card receives both video and audio signal from the outside source and conversion from analog to digital signal takes place. This process of conversion is known as sampling.This process converts the analog signal to digital data streams so that this signal can be stored in binary data format of 0's and 1's.This digital data stream is then compressed using the video capturing software and stores them in the hard disk as a file. This file is then used for incorporation into multimedia.This digitized file can also be edited according to the requirements using various editing software such as Adobe Premiere.


A number of digitizer or video grabbing cards are available in the market. However, one from Intel called Intel Smart Video Recorder III does a very good job of capturing and compressing video.


(d) Sound Card


Today's computers are capable of creating the professional multimedia needs. Not only you can use computer to compose your own music, but it can also be used for recognition of speech and synthesis. It can even read back the entire document for you.But before all this happens, we need to convert the conventional sound signal to computer understandable digital signals.This is done using a special component added to the system called sound card. This is installed into a free slot on the computer motherboard. As in the case of video grabber card, sound card will take the sound input from outside source (such as human voice, pre-recorded sounds, natural sounds etc.) and convert them into digital sound signal of 0's and 1's.The recording software used alongwith the sound card will store this digitised sound stream in a file. This file can latter be used with multimedia software. One can even edit the digitised sound file and add special sound effects into it.


Most popular sound card is from Creative Systems such as Sound Blaster-16, AWE, etc. AWE sound card supports 16 channel,voice and 18 instruments and 10 drums sound reproduction. It also has CD-ROM interface.


(e) CD-ROM Drive


CD-ROM is a magnetic disk of 4.7 inches diameter and it can contain data up to 680 Megabytes. It has become a standard by itself basically for its massive storage capacity, faster data transfer rate. To access CD-ROM a very special drive is required and it is known as CD-ROM drive. Let us look into the term ROM that stands for 'Read Only Memory'. It means the material contained in it can be read (as many times, as you like) but the content cannot be changed.


As multimedia involves high resolution of graphics, high quality video and sound, it requires large amount of storage space and at the same time require a media, which can support faster data transfer. CD-ROM solves this problem by satisfying both requirements.


Similar to the hard disk drive, the CD-ROM drive has certain specification which will help to decide which drive suit best to your multimedia requirement.


(i) Transfer Rate


Transfer rate is basically the amount of data the drive is capable of transferring at a sustained rate from the CD to the CPU. This is measured in KB per second. For example, 1x drive is capable of transferring 150KB of data from the CD to the CPU. In other terms 1x CD drive will sustain a transfer rate of 150KB/sec, where x stands for 150 KB. This is the base measurement and all higher rates are multiple of this number, x. Latest CD-ROM drive available is of 64x, that means it is capable of sustaining a data transfer rate of 64x150=600 KB =.8MB per second from the CD to the CPU.


(ii) Average Seek time


The amount of time lapses between request and its delivery is known as average seeks time. The lower the value better the result and time is measured in milliseconds. A good access time is 150ms.


Recently computer technology has made tremendous progress. You can now have CDs which can 'write many, read many' times. This means you can write your files in to a blank CD through a laser beam. The written material can be read many times and they can even be erased and re-written again. Basically this re-writable CD's can be used a simple floppy disk.


(f) Scanner


Multimedia requires high quality of images, graphics to be used. And it takes lot of time creating them. However there are ready-made sources such as real life photographs, books, arts, etc. available from where one easily digitized the required pictures. To convert these photographs to digital format, one need a small piece of equipment called scanner attached to the computer. A scanner is a piece of computer hardware that sends a beam of light across a picture or document and records it. It captures images from various sources such as photograph, poster, magazine, book, and similar sources. These pictures then can be displayed and edited on a computer.The captured or scanned pictures can be stored in various formats like;


File FormatExplanation


PICT- A widely used format compatible with most Macintosh


JPEG- Joint Photographic Experts Group - a format that compresses files and lets youchoose compression versus quality


TIFF-Tagged Image File Format - a widely used format compatible with both Macintosh and Windows systems


Windows BMP- A format commonly used on MS-DOS and MS-Windows computers


GIF - Graphics Interchange Format - a format used on the Internet, GIF supports only 56 colours or grays


Scanners are available in various shapes and sizes like hand-held, feed-in, and flatbed types. They are also for scanning black-and-white only or color.Some of the reputed vendors of scanner are Epson, Hewlett-Packard, Microtek and Relisys.


(g) Touchscreen


As the name suggests, touchscreen is used where the user is required to touch the surface of the screen or monitor. It is basically a monitor that allows user to interact with computer by touching the display screen. This uses beams of infrared light that are projected across the screen surface. Interrupting the beams generates an electronic signal identifying the location of the screen. And the associated software interprets the signal and performs the required action. For example, touching the screen twice in quick succession works as double clicking of the mouse. Imagine how useful this will be for visually handicapped people who can identify things by touching a surface. Touchscreen is normally not used for development of multimedia, it is rather used for multimedia presentation arena like trade show, information kiosk, etc.


5.5 USES OF MULTIMEDIA


Placing the media in a perspective within the instructional process is an important role of the teacher and library professional. Following are the possible areas of application of multimedia


?Can be used as reinforcement


?Can be used to clarify or symbolize a concept


?Creates the positive attitude of individuals toward what they are learning and the learning process itself can be enhanced.


?The content of a topic can be more carefully selected and organized


?The teaching and learning can be more interesting and interactive


?The delivery of instruction can be more standardized.


?The length of time needed for instruction can be reduced.


?The instruction can be provided when and where desired or necessary.
