An Ethernet standard that transmits at 10 Mbps over twisted wire pairs (telephone wire). 10Base-T was the first version of Ethernet to use a star architecture. When used with a hub, 10Base-T shares the 10 Mbps bandwidth between all the ports. When used with a switch, each transmit/receive pair has the full 10 Mbps.
Today, most Ethernet adapters, hubs and switches are 10/100/1000 devices, which support 10, 100 and 1000 Mbps (10Base-T, 100Base-T and 1000Base-T). See

T Means Twisted
In the 1980s, 10Base-T was widely deployed. Using inexpensive and flexible twisted pair "telephone wire," 10Base-T Ethernet was much easier to install than previous "thick" and "thin" Ethernets that used coaxial cable. See

A Star Configuration
All stations in modern Ethernet networks are wired to a switch using twisted pair wires and RJ-45 connectors. There can be many switches in a network.
