Fast EthernetFast Ethernet
is a collective term a number of Ethernet
standards that carry traffic at the nominal rate of 100 Mbit/s, against the original Ethernet speed of 10 Mbit/s.
Fast Ethernet is no longer the fastest form of Ethernet: Gigabit Ethernet and the new 10 Gigabit Ethernet standards are 10 respectively 100 times faster.
