Ethernet

__ETHERNET__ The Ethernet is a family of frame based computer networking technologies for local area networks It defines a number of wiring and signaling standards for the Physical Layer of the OSI networking model, through means of network access at the Media Access Control (MAC) /Data Link Layer, and a common addressing format. The Ethernet standard defines everything about modern network hardware, from the physical size and shape of the conector on the end of the network cable-called an RJ-45.

If two computers dont have the same network technology, they cant network together. Hubs and switches function quite differently when they receive an ethernet frame. A hub reapets the frame down every network cable connected, hoping one of the computers connected is the requesting machine. A switch learns the network address of every machine connected to it, reads the recipient address on the frames, and sends them along only in the appropriate connection.Landlocked devises continue to plug into etherbet cables, but the switch also sends out a signal inviting Wi-Fi-enable devices to connect to the networks. Only one piece of data can be in the ethernet at the time.
