A Brief Summary of Ethernet

Ethernet dates back to the late 1960s, when Norman Abramson designed the University of Hawaii's Aloha radio network. It connected the IBM mainframe on the island of Oahu to the other islands and ships at sea.

Bob Metcalfe was working for Xerox Corporation's Palo Alto Research Center (PARC) in the early 1970s. He stumbled across the earlier work of Abramson during his task to connect the ALTO (first PC with a graphical user interface) to ARPANET. The Alto Aloha Network first ran in 1973, and Bob Metcalfe talked about the physical medium as ether. The original Ethernet bandwidth was 2.94 Mbps.
