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.
