Ethernet
The most common type of LAN, was originally developed by DEC, Intel, and Xerox, and it was called DIX Ethernet. It later came to be called thick Ethernet because of the thickness of the cable used in this type of network, and because it ran at 10 Mbps. The standard for Ethernet was updated in the 1980s to add more capability. The new version of Ethernet was referred to as Ethernet II, or thin Ethernet. The Type II frame identifies the upper-layer protocol using an "Ethertype" field in the frame header.
