Network Evolution (Early Internet)
In the late 1970’s and early 1980’s, ARPA (Advanced Research Projects Agency) started to test networks for peer-to-peer computer communication and terminal support on a national scale.
By the mid 1980’s this network became available to the universities and NSF (National Science Foundation) started funding university connectivity.
Early applications of these networks included electronic mail, downloading large data sets (ftp) and remote access to computers (telnet).
