Fast Ethernet (FE) ndi mawu oti Ethernet pamanetiweki apakompyuta, omwe amapereka kusamutsa kwa 100Mbps. Muyezo wa IEEE 802.3u 100BASE-T Fast Ethernet udayambitsidwa ndi IEEE mu 1995, ndipo kufalikira kwa Ethernet mwachangu kale kunali 10Mbps. Muyezo wa Fast Ethernet umaphatikizapo magawo atatu: 100BASE-FX, 100BASE-TX, ndi 100BASE-T4. 100 ikuwonetsa kufalikira kwa 100Mbit / s. "BASE" amatanthauza kutumiza kwa bandeji; Kalata ikadutsa pamzerewu imatanthawuza njira yotumizira chizindikiro, "T" imayimira awiri opindika (mkuwa), "F" imayimira nsonga ya kuwala; Chilembo chomaliza (chilembo "X", nambala "4", ndi zina zotero) chimatanthawuza njira ya mzere wogwiritsidwa ntchito. Gome lotsatirali likuwonetsa mitundu yodziwika bwino ya Efaneti.
Poyerekeza ndi Efaneti wachangu, Gigabit Efaneti (GE) ikhoza kupereka kutengerapo kwa 1000Mbps pamaneti apakompyuta. Muyezo wa Gigabit Efaneti (wotchedwa IEEE 802.3ab standard) unasindikizidwa mwalamulo ndi IEEE mu 1999, patangopita zaka zochepa kuchokera pakubwera kwa Fast Ethernet muyezo, koma sunagwiritsidwe ntchito kwambiri mpaka cha 2010. Gigabit Efaneti akutenga mawonekedwe a chimango. ya IEEE 803.2 Efaneti ndi njira ya CSMA/CD media access control, yomwe imatha kugwira ntchito mu theka la duplex ndi duplex mode. Gigabit Ethernet ili ndi zingwe ndi zida zofanana ndi Fast Ethernet, koma ndizosunthika komanso zotsika mtengo. Ndi chitukuko chokhazikika cha Gigabit Ethernet, matembenuzidwe apamwamba kwambiri awonekera, monga 40G Ethernet ndi 100G Ethernet. Gigabit Ethernet ili ndi magawo osiyanasiyana osanjikiza thupi, monga 1000BASE-X, 1000BASE-T, ndi 1000BASE-CX.
