#830 The history of the Internet
因特网的历史
We are all busy talking about and using the Internet (因特网), 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 (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 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 (软件) that made "surfing" (浏览) the Internet
more convenient (方便).
Today it is easy to get on-line (上网) and it is said that millions of
people use the Internet every day. Sending e-mail (电子邮件) is
more and more popular among students.
The Internet has now become one of the most important parts
of people's life.
