Ethernet is a standard originally developed by the Xerox Corporation for use in local area networks (LANs). It can link several devices on one cable – all devices linked to the cable can communicate with any other device on the cable.

Many Ethernet networks originally used coaxial cable (and this is still used in some very large ethernet LANs) but now ethernet networks commonly use twisted pair wires.

Ethernet originally  transmitted data at up to 10Mb. However there is also now Fast Ethernet, which transmits at up to 100Mb, and Gigabit Ethernet transmitting at up to 1000Mb.

The Ethernet protocol is set out in the standard IEEE 802.3
