Ethernet refers to the family of local-area networks (LANs) covered by the IEEE 802.3 standard. This standard also defines what is commonly known as the Carrier Sense Multiple Access/Collision Detect (CSMA/CD) protocol.

The Xerox Corporation Palo Alto Research Center (PARC) developed the original Ethernet as an experimental coaxial-cable network in the 1970s. This Ethernet operated with a data rate of 3 megabits per second (Mbps) using a carrier sense multiple access collision detect (CSMA/CD) protocol for LANs, and was designed for networks with intermittent heavy traffic requirements. Success with this project led to the 1980 joint development of the 10 Mbps Ethernet (Version 1.0) specification by the three-company ...
