Fast Ethernet (FE) waa ereyga Ethernet ee isku xirka kombiyuutarka, kaas oo bixiya xadiga wareejinta 100Mbps. Heerka IEEE 802.3u 100BASE-T Fast Ethernet waxaa si rasmi ah u soo bandhigay IEEE sanadkii 1995-kii, heerka gudbinta xawaaraha Ethernet-na wuxuu hore u ahaa 10Mbps. Halbeegga Ethernet Fast waxa ku jira saddex qaybood oo kala ah: 100BASE-FX, 100BASE-TX, iyo 100BASE-T4. 100 ayaa tilmaamaya heerka gudbinta 100Mbit/s. "BASE" waxaa loola jeedaa gudbinta gundhigga; Xarafka ka dib xariijimaha wuxuu tilmaamayaa dhexdhexaadiyaha gudbinta ee sidda calaamadda, "T" waxay u taagan tahay lammaane maroojin ah (naxaas), "F" waxay u taagan tahay fiber indhaha; Dabeecadda u dambaysa (xaraf "X", nambarka "4", iwm) waxa uu tilmaamayaa habka koodka xariiqda ee la isticmaalo. Jadwalka soo socdaa wuxuu muujinayaa noocyada Ethernet-ka ee degdega ah ee caadiga ah.
Marka la barbar dhigo Ethernet degdega ah, Gigabit Ethernet (GE) waxa ay ku siin kartaa xawilaadda xawilaadda 1000Mbps ee shabakada kombuyuutarka. Heerka Gigabit Ethernet (oo loo yaqaan IEEE 802.3ab standard) waxaa si rasmi ah u daabacay IEEE 1999, dhowr sano ka dib imaatinka heerka Fast Ethernet, laakiin si weyn looma isticmaalin ilaa qiyaastii 2010. Gigabit Ethernet wuxuu qaataa qaabka jir ee IEEE 803.2 Ethernet iyo habka CSMA/CD ee marin u helka warbaahinta, kaas oo ku shaqayn kara laba-duplex iyo qaab laba-dule oo buuxa. Gigabit Ethernet waxay leedahay fiilooyinka iyo qalabka la midka ah ee Fast Ethernet, laakiin waa wax badan oo la taaban karo oo dhaqaale ah. Iyadoo horumarinta joogtada ah ee Gigabit Ethernet, noocyo aad u horumarsan ayaa soo muuqday, sida 40G Ethernet iyo 100G Ethernet. Gigabit Ethernet waxay leedahay heerar lakabka jirka oo kala duwan, sida 1000BASE-X, 1000BASE-T, iyo 1000BASE-CX.
