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.

One of the greatest problems for those settlers in Nebraska in the last quarter of the previous century was fuel.
