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 switching. Owing to this technology, if some computers on the network are knocked out information will just route around them. One such packet-switching 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 USA, while the rest are located in more than 100 countries. Although the number of host computers can be counted fairly accurately, nobody knows 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 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 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.
However, some problems remain. The most important is security. When you sale an e-mail message to somebody, this message can travel through many different networks and computers. The data are 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 encoding. But when it becomes necessary to send important information over the network, these encoding programs may be useful. However, there are still both commercial and technical problems which will take time to be resolved.
