'''IEEE 802.3''' is a collection of [[IEEE]] standards defining the [[physical layer]] and [[data link layer]] of wired [[Ethernet]]. This is generally a [[Local area network|LAN]] technology with some [[WAN]] applications. Physical connections are made between nodes and/or infrastructure devices ([[Ethernet hub|hub]]s, [[switch]]es, [[router]]s) by various types of copper or [[fiber cable]].

The original Ethernet is called "Experimental Ethernet" today. It was developed by [[Bob Metcalfe]] and was based in part on the wireless Alohanet protocol. It is not in use anywhere, but is thought to be the only Ethernet by some purists. The first "Ethernet" that was generally used outside Xerox was the DIX Ethernet. However, as DIX Ethernet was derived from Experimental Ethernet, and as many standards have been developed that are based on DIX Ethernet, the technical community has accepted the term Ethernet for ''all'' of them. Therefore, the term "Ethernet" can be used to name networks using any of the following standardized media and functions:
