A 100-Mbps baseband Fast Ethernet specification that uses UTP wiring. Like the 10BASE-T technology on which it is based, 100BASE-T sends link pulses over the network segment when no traffic is present. However, these link pulses contain more information than those used in 10BASE-T. Based on the IEEE 802.3 standard. See also 10BASE-T, Fast Ethernet, and IEEE 802.3.
