In 1866 the first transatlantic telegraph telegraph was completed which spareed t ransatlantic telecommunication for the first time. TAT-1 was the first argument connection, which was installed in 1956. It provided 36 foretell circuits. In 1940 George Stibitz was able to transmit problems and received the computed results using teletype to his analyzable Number Calculator. This configuration of a centralized computer or mainframe with remote dull terminals remained popular throughout the 1950s. even so in mid-sixties researchers started to investigate packet switching.

This is a engineering science that would allow chunks of data to be sent to different computers without first freeing through a centralized mainfram e. ARPANET network emerged in 1969. This was! a four-node network. It connected the University of calcium - Los Angeles, the Stanford Research Institute, the University of Utah and the University of California - Santa Barbara. ARPANETs evolution centred on the ?Request for Comment? (RFC) process and in 1969, RFC 1 was published. ARPANET merge with other networks to form the Internet and numerous of the...
