In [[computer network]]ing, '''Fast Ethernet''' [[Ethernet physical layer|physical layers]] carry traffic at the nominal rate of {{nowrap|100 Mbit/s}}. The [[Classic Ethernet|prior Ethernet]] speed was {{nowrap|10 Mbit/s}}. Of the Fast Ethernet physical layers, '''100BASE-TX''' is by far the most common.

Fast Ethernet was introduced in 1995 as the '''IEEE 802.3u''' standard<ref>{{cite book| doi = 10.1109/IEEESTD.1995.7974916|title=IEEE 802.3u-1995|date=October 26, 1995|publisher=[[IEEE]]|isbn=978-0-7381-0276-4}}</ref> and remained the fastest version of Ethernet for three years before the introduction of [[Gigabit Ethernet]].<ref>{{cite journal |author=H.
