We are all busy talking about and using the Internet,but how many of us know the history of the Internet?Many people were surpris ed that the Internet was built 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 people built a new system .If one computer didn’t work ,the new network system can go 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 the 1990s,computers became cheaper and easier to use.
