First operational packet switching network

ARPANET (Advanced Research Projects Agency Network), allowed the protected flow of information between military installations, as well as allowing researchers access to the few powerful computers in the USA remotely. The first four locations linked via ARPANET were the University of California, in Santa Barbara and Los Angeles, Stanford Research Institute, and the University of Utah. At 22:30 on 29 October 1969 the first message was sent, from UCLA to Stanford. The message was intended to be ‘log win’, and the researchers at Stanford watched as the saw the ‘l’ and ‘o’. The system crashed when UCLA typed the ‘g’. ARPANET was the first operational packet switching network.
