I.Look through the list of the English words and their Russian equivalents facilitating reading text C:
interactive – интерактивный; traffic – нагрузка; processing – обработка; terminal – конечная станция; carrier – (многоканальная) система передачи информации с использованием несущей; to reject – отказываться; unwanted – нежелательный, ненужный.
П.Study the questions below and find out which of them the author answers in the text:
1. Is Very Large-Scale Integration (VLSI) revolution nearing its end? 2. What will one be able to do with intelligent network? 3. Many uses of the telephone will be replaced by an electronic in-basket, won't they? 4. Will the postal service undergo great changes in the third millennium? 5. To .what extent will the number of newspapers and magazines be decreased in the third millennium? 6. Can one give an exact date of introducing inexpensive graphics terminals in the home?
Information and Communication in the Third Millennium
1. By the beginning of the third millennium, the Very Large-Scale Integration (VLSI)1 revolution will at last be nearing its end. We will see some of the results below – intelligent networks with information as well as data processing2. In fact, much of the interactive multiterminal communication traffic will be routed through networks with delay and computation at the nodes. As one example of what we mean by information as opposed to data processing, one will be able to route a call or electronic message to a known person without necessarily having to know the equivalent of his "telephone number". One will be able to conduct a dialogue3 over the terminal with an intelligent network that will in effect give one the number or address.
2. Commercial video broadcasting4 over the air will be almost entirely replaced by scheduled, or even on demand, transmission into homes via fibre optics5.
3. Many uses of the telephone will be replaced by an electronic in-basket that provides message forwarding, editing, retrieval, and redirection services. The Bell System will still exist, but will only be one carrier of several, depending on the kind of service. In any case, most terminals will be procured separately from the carriers, which will be mainly transmission companies or information services, depending on what they feel like calling themselves.
4. Newspapers and magazines, particularly specialized ones, will still exist. However, by the beginning of the third millennium, a trend will have been set which will lead to their ultimate redefinition as electronic services6 instead of as pieces of paper. Inexpensive graphics terminals7 in the home will permit this new kind of publication. In some cases, hard copy will be available, although with local disk storage this will not be so necessary. The electronic in-basket and electronic newspapers will mean the end of the postal service as we wish we knew it. It will be restricted to packages. The problem of electronic junk mail can be solved by each individual programming his or her own terminal to reject unwanted communications as they see fit9.
1) VLSI (Very Large-Scale Integration )– сверхбольшая интегральная схема
2) data processing – обработка данных
3) to conduct a dialogue – вести разговор, беседу
4) video broadcasting– видеопередача
5) via fibre optics – через волоконную оптику
6) electronic services – электронные службы
7) graphics terminal – графический терминал
8) hard copy – копия на однократно используемом носителе
9) as they see fit – на их усмотрение
III. Say whether the following statements are true or false:
1. Very Large-Scale Integration revolution (VLSI) will be nearing its end by the beginning of the third millennium. 2. It will bring great disadvantages for communication system. 3. Terminals of the future will give out numbers or addresses for conducting dialogues. 4. Fibre optics will find most varied application in future intelligent communication network. 5. Application of fibre optics for communication will mean complete disappearance of the Bell System as well as the postal service. 6. Each individual will have a possibility to program his or her own terminal to reject unwanted communications.
IV.Say how one will be able to conduct a dialogue over the terminal with an intelligent network.
a) what commercial video broadcasting over the air will be replaced by; b) what the electronic in-basket and electronic newspapers will mean in the future.
VI.Find the main information of paragraph 4.
VII. Read paragraph 4 again and say:
a) whether newspapers and magazines will exist in the third millennium; b) how newspapers and magazines will be redefined; c) what inexpensive graphics terminals will permit; d) whether hard copy will be available; e) whether the problem of electronic junk can be solved by individual programming of terminals.
VIII. Summarize the general ideas developed in texts А, В and С
IX.Imagine that you are to make a report about the future trends in the system of communication at a scientific conference. While preparing it use the information of texts А, В and С. Make the report orally.
Key to Lesson 3: The title of the text is "Communicating with Glass and Light".
