 Many people were surprised when the Internet was set up in the 1960s. At that time,computers were large and expensive. Computer network (網(wǎng)絡(luò)) didn't work well. If one computer in the network broke down,then the whole network system (系統(tǒng)) stopped. So people needed to build a new network system. If part of the network was not working,people could use another part to send information. In this way the computer network system would keep on working all the time.

  Only the government (政府) used the Internet in the past,but in the early 1970s,universities,hospitals and banks began to use it. By the beginning of the 1990s,computers became cheaper and easier to use.
