Ethernet
Definition
A local-area network (LAN) protocol that is specified in IEEE 802.3 and that uses CSMA-CD to provide 10 Mbps service over copper. Switched Ethernet provides faster service (e.g., 100 Mbps Ethernet, 10GigE). Gigabit (GB) and 10 GB Ethernet service are now possible. GB Ethernet is used mainly for backbone services and wide area networking.
