Ethernet LANs: A collection of devices, including user devices, LAN switches, routers, old hubs, and cables, all of which use IEEE Ethernet standards at the physical and data link layers, so that the devices can send Ethernet frames to each other.
802.3: The name of the original IEEE Ethernet standard, as well as the overall base name of all IEEE Ethernet LAN working committees.
Fast Ethernet: The informal name for one particular Ethernet standard, originally defined formally as 802.3u, which was the first Ethernet standard to surpass the original 10-Mbps speed to run at 100 Mbps.
Gigabit Ethernet: The informal name for one particular Ethernet standard, defined formally in
802.3z (for fiber) and

Ethernet LANs deliver Ethernet frames from one Ethernet device to another.
10BASE-T: The common name for one of several standards that are part of the IEEE Ethernet 802.3i standard. This standard uses two twisted pairs in a UTP cable, with a bit rate of 10 Mbps.
100BASE-T: A term that refers to all Fast Ethernet standards, including 100BASE-Tx, which refers to the one Fast Ethernet standard that uses two pairs in a UTP cable.
1000BASE-T: A particular Ethernet standard shortcut name, also known by the formal standard 802.3ab, which defines 1000-Mbps (1-Gbps) operation, star topology, using four-pair UTP cabling.
10GBASE-T: A particular Ethernet standard shortcut name, also known by the formal standard 802.3an, that defines 10-Gbps operation, star topology, using four-pair UTP cabling.
Metro Ethernet: A type of multiaccess WAN service that uses Ethernet as the physical access link and usually uses an Ethernet switch as the customer site device, with the customer sending
Ethernet frames from one customer site to the other.
Token Ring: An old LAN technology, popularized by IBM and standardized by IEEE as standard 802.5, that competed with Ethernet LANs in the 1980s and 1990s.
LAN Edge: A reference to the part of the campus LAN with the end-user devices and the switches to which they connect,
