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 (建立) in the 1960s. At that time,
computers were large and expensive. Computer network (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 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, hospitals
and banks were allowed to use it, too. However, computers were still very expensive and the Internet was

developed software that made"surfing" the Internet easier.

is more and more popular among young people. The Internet has now become one of the most important parts
