Ethernet

特許 権利維持 Ethernet /ˈiːθərnɛt/ is a family of computer networking technologies for local area (LAN) and larger networks. It was commercially introduced in 1980 while it was first standardized in 1983 as IEEE 802.3,[1] and has since been refined to support higher bit rates and longer link distances. Over time, Ethernet has largely replaced competing wired LAN technologies such as token ring, FDDI, and ARCNET. The primary alternative for contemporary LANs is not a wired standard, but instead a wireless LAN standardized as IEEE 802.11 and also known as Wi-Fi.
