Ethernet

Ethernet evolved from a 9.6 kilobit-per-second (Kbps) radio transmission system developed at the University of Hawaii called ALOHA. A key feature of ALOHA was that all transmitters shared the same channel and contended for access to the channel to transmit. This became the basis for the contention-based Ethernet that we know today.

In 1972, the Xerox Corporation created a 2.94-megabit-per-second (Mbps) network based on the principles of the ALOHA system. This new network, called Ethernet, featured carrier sense, in which the transmitter listens before attempting to transmit. In 1979, Digital, Intel, and Xerox (DIX) created an industry standard 10-Mbps Ethernet known as Ethernet II. In 1981, the IEEE Project 802 formed the 802.3 subcommittee ...
