In
1969, the U.S. Defense Department’s Advanced
Research Projects Agency (ARPA) began to
construct a resource sharing computer network
among its contractors. This network became known
as the ARPAnet, a wildly successful wide-area
packet switching network that later evolved into
the Internet. By 1970, the initial four-node
configuration was complete consisting of UCLA, UC
Santa Barbara, Stanford Research Institute and
the University of Utah. From these four sites,
the network expanded to thirteen by January 1971
and twenty-three by April 1972. By the time that
DIGITAL joined as the first computer company in
1977, there were approximately 60 nodes in
operation. |
