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,computer networks didn't work
well.If one computer in the network broke down, then the whole network stopped.

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,I'm daydaytest Placeholder

universities, hospitals and banks were allowed to use it, too. However, computers

day. Sending e-mail is more and more popular among people.
