Formerly called Alto Aloha Community, Ethernet is a popular regional-area network (LAN) process initially developed by Xerox PARC in 1973 by Robert Metcalfe among others (U.S. Patent #4,063,220).
Ethernet port can be used to connect your computer to another computer, a local network, or an external DSL or cable modem.
Being the initial community to supply Carrier Sense Multiple Access / Collision Detection (CSMA/CD), Ethernet is just a quick and reliable system solution that’s still popular today.
Since its commercial release, Ethernet has retained a good degree of backward compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols. The primary alternative for some uses of contemporary LANs is Wi-Fi, a wireless protocol standardized as IEEE 802.11.
