Ethernet

Ethernet Ethernet In early 1970’s, Xerox Corporation introduced a different networking concept called Ethernet. The thick coaxial media system was the first media system specified in the original Ethernet standard of 1980. Today most sites use twisted-pair media for connections to the desktop. Ethernet is designed to run on a single transmission line to which all stations are connected. As with token ring, Ethernet is peer-to-peer; however no monitoring device is requires. Unlike token ring, Ethernet does not require that stations wait for a token to be passed before transmitting. Stations are able to connect directly to one another and pass data any time there is no activity on the network. The 10-Mbps Ethernet media varieties include the original thick coaxial system, as well as thin coaxial, twisted-pair, and fiber optic systems. The most recent Ethernet standard defines the new 100-Mbps Fast Ethernet systems that operate over twisted-pair and fiber optic media. Picture of the first Ethernet There are several LAN technologies in use today, but Ethernet is by far the most popular. Industry estimates indicate that as of 1994 over 40 million Ethernet nodes had been installed worldwide.
