Advanced Research Projects Agency Network
(ARPANET) A pioneering longhaul wide area
network funded by DARPA (when it was still called "ARPA"?).
It became operational in 1968 and served as the basis for
early networking research, as well as a central backbone
during the development of the Internet. The ARPANET
consisted of individual packet switching computers
interconnected by leased lines. Protocols used include
FTP and telnet. It has now been replaced by NSFnet.
