THE INTERNET

The Internet is a huge network of computers. Called “the mother of all networks,” the Internet, or simply “the Net,” is an international network connecting approximately 36,000 smaller networks. The Internet is very helpful, because it is a huge database of knowledge. The Internet, a global computer network which embraces millions of users all over the world, began in the United States in 1969 as a military experiment. It was designed to survive a nuclear war. Information sent over the Internet takes the shortest path available from one computer to another. Because of this, any two computers of the Internet will be able to stay in touch with each other as long as there is a single route between them. This technology is called packet switching. Owing to this technology, if some computers on the network are knocked out (by a nuclear explosion, for example), information will just route around them. One such packet-switching network already survived a war. It was the Iraqi computer network which was not knocked out during the Gulf War.

Most of the Internet host computers (more than 50 %) are in the United States, while the rest are located in more than 100 other countries. Although the number of host computers can be counted fairly accurately, nobody knows exactly how many people use the Internet, there are millions, and their number is growing by thousands each month worldwide.

Everyone should have the Internet as a means of communication. The most popular Internet service is e-mail. Most of the people, who have access to the Internet, use the network only for sending and receiving e-mail messages. However, other popular services are available on the Internet: reading USENET News, using the World- Wide Web, telnet, FTP, and Gopher.

In many developing countries the Internet may provide businessmen with a reliable alternative to the expensive and unreliable telecommunications systems of these countries. Commercial users can communicate over the Internet with the rest of the world and can do it very cheaply. When they send email messages, they only have to pay for phone calls to their local service providers, not for calls across their countries or around the world. But who actually pays for sending e-mail messages over the Internet long distances, around the world? The answer is very simple: an user pays he/ her service provider a monthly or hourly fee. Part of this fee goes towards its costs to connect to a larger service provider. And part of the fee got by the larger provider goes to cover its cost of running a worldwide network of wires and wireless stations.

But saving money is only the first step. If people see that they can make money from the Internet, commercial use of this network will drastically increase. For example, some western architecture companies and garment centers already transmit their basic designs and concepts over the Internet into China, where they are reworked and refined by skilled- but inexpensive- Chinese computer aided- design specialists.

However, some problems remain. The most important is security. When you send an e-mail message to somebody, this message can travel through many different networks and computers. The data is constantly being directed towards its destination by special computers called routers. Because of this, it is possible to get into any of computers along the route, intercept and even change the data being sent over the Internet. In spite of the fact that there are many strong encoding programs available, nearly all the information being sent over the Internet is transmitted without any form of encoding, i.e. “in the clear”. But when it becomes necessary to send important information over the network, these encoding programs may be useful. Some American banks and companies even conduct transactions over the Internet. However, there are still both commercial and technical problems which will take time to be resolved.

VI. Answer the questions: 1. What is Internet? 2. How did it start / appear? 3. How many Internet users are there in the world? 4. What is the path of the information sent over Internet? 5. What is the most popular Internet service? 6. Are Internet services expensive? 7. Why is it possible to intercept or even change the data, while they are travelling to the point of their destination? 8. Is the information sent over Internet coded? 9. What can be done with the help of Internet?

VII.Practice.

Task 1. Match the phrases with their Russian equivalents:

1. global network A. почасовая оплата

2. garment center B. развивающаяся страна

3. developing country C. благодаря этому.

4. shortest path available D. глобальная сеть

5. growing number E. центр изготовления одежды

6. hourly fee F. кратчайший свободный

7. owing to this G. возрастающее число

1-d 2- e 3-b 4-f 5-g 6-a 7-c

Task 2. Find English equivalents to the following phrases: 1. экономить деньги; 2. Пережить атомную войну; 3. Направляться; 4. Общаться по…; 5. Получать сообщения; 6. Поддерживать контакты; 7. Катастрофически
74 возрастать; 8. Проводить сделки; 9. Решать проблемы; 10. Точно подсчитать 11. Включать миллионы пользователей; 12. Перехватить
сообщение

*** (To resolve problems, to receive messages, to intercept a message, to survive a nuclear war, to be in touch, to embrace millions of users, to count accurately, to communicate over… , to increase drastically, to save money, to conduct transactions, to be directed (to)).

Task 3. Translate the following sentences into English: 1. Интернет – глобальная компьютерная сеть, которая насчитывает миллионы пользователей во внешнем мире. 2. Сеть выросла из военного эксперимента, который начался в США в 1969г. 3. Целью его было выживание в ходе ядерной войны. 4. Информация, посылаемая по Интернету, идет от одного компьютера к другому по кратчайшему возможному пути. 5. Никто не может точно подсчитать, сколько людей в мире пользуются Интернетом, ибо их миллионы и число это ежемесячно возрастает на несколько тысяч. 6. Большинство людей, которые имеют доступ к Интернету, используют Сеть только для передачи и получения сообщений. 7. Но есть и другие услуги, предоставляемые Интернетом. 8. Во многих развивающихся странах Интернет может обеспечить бизнесменов надёжной связью, в отличие от дорогих и ненадёжных систем телекоммуникации. 9. Кто же на самом деле оплачивает отправку сообщений по Интернету на дальние расстояния? Ответ прост: пользователь платит ежемесячную плату фирме- поставщику электронных услуг (провайдеру). 10. Все остальные вопросы решает провайдер. 11. Экономия денег- не единственное преимущество Интернета. 12. В настоящее время многое можно осуществлять через Интернет, в том числе проведение сделок.

VIII. Physical training. Здоровьесберегающая физкультминутка

IX. Работа с одаренными детьми. Презентация

What are the advantages and disadvantages of using the internet?

Student 1.

I think using internet has more advantages then disadvantages.

  • Internet is fast and easy to use.

  • It gives access to a lot of information.

  • There are a lot of information . Some of them are very useful in our job other helps in our hobby.

  • In the Internet we can find everything we want.

  • Internet can help us to find data on any subject that we need.

  • We can also do shopping using Internet.There are many online stores and sites that can be used to look for products and buy them .

  • With e-mail we can send and receive electronic messages.

Student 2.

Beside a lot of advantages, Internet has some disadvantages too.

  • People who spend too much time sitting in the front of computer can easily gets ill.

  • Radiation emitted by computer’s screen is harmful to eyes.

  • People who spend too much time at their homes are getting weaker because they can do everything using Internet.

  • Sitting for a long time is also harmful to the spine. 
    Internet can by addictive because some people just can’t live without it.

  • People have no real friends and when Internet is down they are getting furious. (свирепый)
