The Two Letters That Began a Network


At 10:30 p.m. Pacific time on October 29, 1969, a message began traveling from a computer at the University of California, Los Angeles, to one at Stanford Research Institute. The intended message was short: LOGIN. It became even shorter when the system crashed after transmitting only the first two letters, LO.
That interrupted attempt was an early test of ARPANET, a network that connected computers at different research institutions. The crash might make the event sound like a failure, but the two letters showed that information could travel between distant computers on the new network. Later that night, the researchers succeeded in completing the login.
Why connect computers?
In the 1960s, computers were expensive machines that often filled large rooms. Researchers used them to perform calculations and run programs, but access to a particular computer and its resources was usually limited to people at or near its location.
Connecting computers promised a way to share resources across distances. A researcher at one institution might be able to use a computer at another without physically traveling there. A network could also help researchers exchange information, though the first ARPANET users did not have the websites and apps people use today.
