The internet, a global computer net
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 on 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 swithing. Owing to this technology, if some computers on the network are knocked out (by a nuclear explosion, for example), information will just rout around them. One such packet- swithing network which has already survived a war is 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 worldwide, and their number is growing by thousands each month.
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 cheaply over the Internet with the rest of the world. When they send e-mail 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: users pay their service provider a monthly or hourly fee. Part of this fee goes toward its costs to connect to a larger service provider, and part of the fee received 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 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 can travel through many different networks and computers. The data is constantly being directed towards its destination by special computers called routers. However, because of this, it is possible to get into any of the computers along the route, intercept and even change the data being sent over the Internet. In spite of the fact that there are many good 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 b 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.

Большинство интернет-главных компьютеров (больше чем 50 %) находится в Объединенном
Государства, в то время как остальные расположены в больше чем 100 других странах.
Хотя число главных компьютеров может быть посчитано справедливо точно, никто не знает точно, сколько людей использует Интернет, во всем мире есть миллионы, и их число растет тысячами каждый месяц.
Во многих развивающихся странах Интернет может предоставить бизнесменам надежную альтернативу дорогим и ненадежным телекоммуникационным системам этих стран. Коммерческие пользователи могут общаться дешево по Интернету с остальной частью мира. Когда они посылают сообщения электронной почты, они только должны заплатить за обращения по телефону их местным поставщикам обслуживания, не за запросы через их страны или вокруг мира. Но кто фактически платит за посылку сообщений электронной почты по Интернету длинные расстояния, вокруг мира? Ответ очень прост: пользователи вносят их поставщику обслуживания ежемесячную или почасовую плату. Часть этой платы идет к ее затратам, чтобы соединиться с большим поставщиком обслуживания, и часть платы, полученной большим поставщиком, идет, чтобы покрыть ее стоимость управления международной сетью проводов и беспроводных станций.
