The Internet has revolutionized the computer and communications world. Do you know the history of the Internet?

It is surprising when people find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time.

In the beginning, the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" the Internet more convenient.

Nowadays, it is easy to surf on the Internet and it is said that millions of people use the Internet every day. Playing computer games and chatting on the Internet are more and more popular among students. The Internet has now become one of the most important parts of people's life.
