Fast Ethernet standard is a networking that supports data transfer rates up to 100 Mbps. 100Base-T is based on the older Ethernet standard . Because it is 10 times faster than Ethernet, it is often referred to as Fast Ethernet. Officially, the 100Base-T standard is IEEE 802.3u.

Like Ethernet, 100BASE-T is based on the CSMA/CDLAN access method. There are several different cabling schemes that can be used with 100BASE-T, including :

100BASE-TX : two pairs of high-quality twisted-pair wires
100BASE-T4 : four pairs of normal-quality twisted-pair wires
100BASE-FX : fiber optic cables

Normal vlan gateway last resort is to network
