At that time, computers were large and expensive. Computer networks 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. 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 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).

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-mails is more and more popular among students.

许多人都惊讶地发现,他们发现互联网成立于20世纪60年代。那时,计算机体积庞大,而且价格昂贵。计算机网络没有工作做好。如果网络上的一台电脑坏了,又整个网络停了下来。所以一个新的网络系统必须被建立起来。这是件好事情,适用于清洁,由许多不同的电脑。如果的一部分,在不工作的时候,网络信息能被送往通过一段。这样的计算机网络系统将继续不停地工作。

起初,互联网只是由政府使用。但是,在二十世纪七十年代早期,大学、医院和银行可以使用它了。然而,计算机还是昂贵,互联网是很难用。20世纪90年代开始的时候,电脑越来越便宜且更容易操作。科学家们也开发的软件,使“冲浪”互联网多非常方便(方便)。

今天就容易在线(上网),据说数百万的人每天都使用互联网。发电子邮件也越来越多的受学生们的欢迎
