Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). The name comes from the physical concept of the ether. It defines a number of wiring and signaling standards for the physical layer, through means of network access at the Media Access Control (MAC)/Data Link Layer, and a common addressing format.

Ethernet is standardized as IEEE 802.3. The combination of the twisted pair versions of Ethernet for connecting end systems to the network, along with the fiber optic versions for site backbones, is the most widespread wired LAN technology. It has been in use from around 1980[1] to the present, largely replacing competing LAN standards such as token ring, FDDI, and ARCNET.

      A Guide to Gigabit and 10G Ethernet Chips (Paid Report)

      The Ethernet market is marked by rapid technology transitions, which often result in large shifts in vendor share. In Ethernet switches, Gigabit Ethernet (GbE) shipments are still growing quickly, displacing Fast Ethernet products. Despite strong competition from incumbent vendors Broadcom and Marvell, new vendors such as Agere and Vitesse are winning designs in this high-growth segment. In servers, the transition to GbE is already complete...
