History of the Internet


Mid 1960  :   Papers on “Packet Switching” emerge.

End 1969s:   ARPA sponsors the development of a

                      packet-switching network, called the

                     ARPANET.
 

1974:   The TCP/IP protocols and model are
 
            being  proposed by Cerf/Kahn.
 

1980:   IPv4 is introduced
 

1983:   ARPANET adopts TCP/IP. At this time,

                     the ARPANET has 200 routers.
 

1984:   NSF funds a TCP/IP based backbone

            network. This backbone grows into the

            NSFNET, which becomes the   successor of

            the ARPANET.
