The data connection sublayers that are necessary for ethernet to function are denoted by the abbreviations llc and mac.
Wide area networks, metropolitan area networks, and local area networks all use members of the Ethernet family of wired computer networking technologies (WAN). Initially standardized as IEEE 802.3 in 1983, it was commercially released in 1980. Since then, Ethernet has undergone refinement to handle faster data rates, a larger number of nodes, and longer link distances while retaining a significant amount of backward compatibility. Competing wired LAN technologies including Token Ring, FDDI, and ARCNET have been mostly superseded by Ethernet over time.
In contrast to the more recent Ethernet variations, which employ twisted pair and fiber optic links in conjunction with switches, the original 10BASE5 Ethernet uses coaxial cable as a shared medium. during the course of its history.
