- Computer networking technology used for local area networks and wireless and metropolitan areanetworks. The Institute of Electrical and Electronics Engineers (IEEE) provides Ethernet standards.
- A widely-used high-speed LAN defined by the IEEE 802.3 standard. Ethernet can use a bus or star topology, utilizes CSMA/CD, and transmits data in variable-length frames of up to 1,518 bytes. There are various versions, the most common utilizing coax cables, while others use twisted pair wiring, or fiber-optic cable. Depending on the version, Ethernet can support data transfer rates from 10 Mbps to over 100 Gbps. Also called Ethernet network.
