Internet?
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 networks(网络) didn't work well. If one computer
in the networks 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(信息)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 goverment(政府),but,in the early 1970s, university(大学),
hospitals and banks were allowed ( ) to use it too. Howerver,computers were still expensive and the
Internet was difficult to become cheaper and easier to use. Scientists had also developed software(软件)
that made "Surfing"(浏览）the Internet more convenient(方便).
