Fast Ethernet (FE) shine kalmar Ethernet a cikin sadarwar kwamfuta, wanda ke ba da saurin canja wuri na 100Mbps. IEEE 802.3u 100BASE-T Fast Ethernet misali an gabatar da shi bisa hukuma ta IEEE a cikin 1995, kuma yawan watsawar Ethernet mai sauri ya kasance a baya 10Mbps. Ma'aunin Ethernet mai sauri ya ƙunshi ƙananan sassa uku: 100BASE-FX, 100BASE-TX, da 100BASE-T4. 100 yana nuna adadin watsawa na 100Mbit/s. “BASE” na nufin watsa igiyar gindi; Harafin bayan dash yana nufin matsakaicin watsawa mai ɗauke da siginar, "T" yana nufin murɗaɗɗen nau'i (jan karfe), "F" yana nufin fiber na gani; Halin ƙarshe (harafin "X", lamba "4", da sauransu) yana nufin hanyar lambar layin da aka yi amfani da ita. Teburin mai zuwa yana nuna nau'ikan Ethernet masu sauri na gama gari.
Idan aka kwatanta da Ethernet mai sauri, Gigabit Ethernet (GE) na iya samar da ƙimar canja wuri na 1000Mbps a cikin hanyar sadarwar kwamfuta. IEEE ne ya buga ma'aunin Gigabit Ethernet (wanda aka fi sani da IEEE 802.3ab misali) a hukumance a shekara ta 1999, 'yan shekaru kadan bayan zuwan ma'aunin Ethernet mai sauri, amma ba a yadu amfani da shi ba sai a kusa da 2010. Gigabit Ethernet yana ɗaukar tsarin tsarin. na IEEE 803.2 Ethernet da CSMA/CD hanyar sarrafa hanyar watsa labarai, wanda zai iya aiki a cikin rabin duplex da cikakken yanayin duplex. Gigabit Ethernet yana da irin igiyoyi da na'urori masu kama da Ethernet Fast, amma ya fi dacewa da tattalin arziki. Tare da ci gaba da ci gaba na Gigabit Ethernet, ƙarin nau'ikan ci gaba sun bayyana, kamar 40G Ethernet da 100G Ethernet. Gigabit Ethernet yana da ma'auni na Layer na jiki daban-daban, kamar 1000BASE-X, 1000BASE-T, da 1000BASE-CX.
