【简答题】
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer network 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 on the time. At first 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 in the Internet” more convenient. Today it is easy to get online and it is said that billions of people use the Internet every day. The Internet has now become one of the most important parts of people’s life.
