[EX Q]: Article: VOIP stands for Voice Over Internet Protocol. It is also referred to as IP Telephony. It is another way of making phone calls, though the 'phone' part is not always present any more, as you can communicate without a telephone set. VOIP is especially popular with long distance calls. The main reason for which people are so massively turning to VOIP technology is the cost. VOIP is said to be cheap, but most people use it for free. Yes, if you have a computer with a microphone and speakers, and a good Internet connection, you can communicate using VOIP for free. There are basically three ways of using VOIP. One is to have a PC on both communicating sides; another is to have a phone on one side and a PC on the other and the third is to have two phones. VOIP is a ly new technology and it has already achieved wide acceptance and use. There is still a lot to improve and it is expected to have major technological advances in VOIP in the future. It has so far proved to be a good candidate for replacing the POTS (Plain Old Telephone System). It, of course, has drawbacks along with the numerous advantages it brings; and its increasing use worldwide is creating new considerations surrounding its regulations and security. The growth of VOIP today can be compared to that of the Internet in the early 90's. The public is getting more and more conscious of the advantages they can get from VOIP at home or in their businesses. Advertising campaigns, which are present everywhere on the net, are contributing a lot towards the popularization of VOIP which not only gives facilities and allows people to save, but also producing huge income for those who dived early into the new phenomenon.

[EX Q]: Article: Criticism is judgement.A critic is a judge.A judgement study and think about the material presented to him, accept it, correct it, or reject it after thinking over what he has read, watched or heard. Another word for criticism is appreciation.When I criticize or appreciate some objector another, I look for its good points and bad points.In reading any printed or written matter, I always have a pencil in hand and put any comments in the book or on a separate paper.In other words, I always talk back to the writer. That sort of critical reading might well be called creative reading because I am thinking along with the author, asking him questions, seeing whether he answers the questions and how well he answers them.I mark the good passages to store them in my memory piece of writing; where, how and why could or should I improve upon it? You might think that doing what I suggested is work.Yes, it is, but the work is a pleasure because I can feel my brain expanding, my emotion reacting and my way of living change. Reading exercises is a great influence on a person.If pictures, still or moving, accompany the reading, the memory will retain the material for a long time. Just as evil books can corrupt, so also can good books gradually work a change on a corrupt person. Let's get back to the beneficial effects of thinking while reading.It helps us to enlarge our minds.We understand more about the universe, its people and many of its wonders.We learn to think and observe in new ways.We certainly do get a feeling for the language we are reading.All good writers in any language have been readers who read critically and continuously.

[EX Q]: Article: Cyberspace, data superhighway, multimedia, for those who have seen the future, and the linking of computers, televisions and telephones will change our lives for ever. Yet for all the talks of a forthcoming technological utopia, little attention has been given to the implications of these developments for the poor. As for all the new high technology, the West concerns itself with the "how", while the question of "for whom" is put aside once again. Economists are only now realizing the full extent to which the communication revolution has affected the world economy. Information technology allows the extension of trade across geographical and industrial boundaries, and transnational corporations take full advantage of it. Terms of trade and exchange, interest rates and money movements are more important than the production of goods. The electronic economy made by information technology allows the haves to increase their control on global markets -- with a destructive impact on the havenots. For them the result is unstable. Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine. As "futures" are traded on computer screens, developing countries simply have less and less control of their destinies. So what are the options of regaining control?One alternative for developing countries is to buy in the latest computers and telecommunications. Yet this leads to long-term dependency and perhaps permanent constraints ( ,) on developing countries' economies. Communication technology is generally exported from the US, Europe or Japan;the patents, skills and ability remain in the hands of a few industrialized countries. It is also expensive, therefore imported products and services must be bought on credit usually provided by the very countries whose companies stand to gain.
