Internet
The Internet, sometimes called simply "the Net," is a worldwide system
of computer networks - a network of networks in which users at any one
computer can, if they have permission, get information from any other
computer (and sometimes talk directly to users at other computers). It
was conceived by the Advanced Research Projects Agency (ARPA) of the
U.S. government in 1969 and was first known as the ARPANet.
The original aim was to create a network that would allow users of a
research computer at one university to "talk to" research computers at
other universities. A side benefit of ARPANet's design was that, because
messages could be routed or rerouted in more than one direction, the
network could continue to function even if parts of it were destroyed in
the event of a military attack or other disaster.
