We talk about and use the Internet every day,but do you know the history of the Internet?
Internet was set up in the 1960s.At that time,computers were large and expensive.Computer networks didn't work.If there is something wrong with one computer in the network,the whole network stopped.So it is necessary to set up a network system (系统).The network system should be so good that many different computers can use it.If part of the network was not working,information could be sent through another part.At first,only the government used the Internet,but in the early 1970s,universities,hospitals and banks used it,too.However,computers were still very expensive.By the start of the 1990s,computers became cheaper and easier to use.Scientists had developed software (软件) and made it easy to surf the Internet.Today it is easy to get on-line.
