We are all busy talking about and using the Internet, but how many of us know the history of the
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).
Today it is easy to get-on-line and it is said that millions of people use the internet every day. Sending
e-mail is more and more popular among students.
