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 network broke down, then
the whole network stopped. So a new network system 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(政府), but in the
early 1970s, universities(大学), hospitals and banks(银行) were allowed(允许)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. Scientists
had also developed software that made "surfing" the Internet more
convenient(方便的).
Today it is easy to get online and it is
said that millions of people use the Internet every day. Sending email is more
and more popular among students.
The Internet has become one of the most
important parts of people's life.
