Many people are surprised when they find that the Internet was set up (建立)in the 1960s . At that time , computers were large and expensive. Computer networks (网络)didn’t work well . If one computer in the network broke down , then the whole network stopped . So a new network system (系统)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.
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 1990s , computers became cheaper and easier to use . Scientists had also developed software that made “surfing”the Internet easier.
