#+title: ethernet
Ethernet is a family of wired computer [[id:c9461f7b-7368-4b88-b90b-2d785fda2159][networking]] technologies commonly used in local area networks ([[id:213d19d9-ca8d-42b1-998a-2f34d1d9cd4c][LAN]]), metropolitan area networks (MAN) and wide area networks ([[id:053d9bdf-c6fe-42ce-8c44-d6945f612bf3][WAN]]). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET.
