Ethernet
A local-area network (LAN) protocol developed by Xerox Corporation in cooperation with DEC and Intel in 1976.
Ethernet uses a bus or star topology and supports data transfer rates of 10 Mbps. It is one of the most widely implemented LAN standards.
A newer version of Ethernet, called 100Base-T (or Fast Ethernet), supports data transfer rates of 100 Mbps. And the newest version, Gigabit Ethernet supports data rates of 1 gigabit (1,000 megabits) per second.
