Fast Ethernet (FE) bụ okwu maka Ethernet na netwọk kọmputa, nke na-enye ọnụego mbufe nke 100Mbps. Ndị IEEE webatara ọkọlọtọ IEEE 802.3u 100BASE-T ngwa ngwa Ethernet na 1995, ọnụego nnyefe nke Ethernet ngwa ngwa bụbu 10Mbps. Ọkọlọtọ Ethernet ngwa ngwa gụnyere ngalaba atọ: 100BASE-FX, 100BASE-TX, na 100BASE-T4. 100 na-egosi ọnụego nnyefe nke 100Mbit / s. "BASE" pụtara mgbasa ozi baseband; Akwụkwọ ozi mgbe akara ntu ahụ na-ezo aka na mgbasa ozi na-ebu akara, "T" na-anọchi anya ụzọ gbagọrọ agbagọ (ọla kọpa), "F" na-anọchi anya eriri anya; Akparamagwa ikpeazụ (akwụkwọ ozi "X", nọmba "4", wdg) na-ezo aka na koodu ahịrị ejiri. Tebụl na-esonụ na-egosi ụdị Ethernet ngwa ngwa.
Tụnyere Ethernet ngwa ngwa, Gigabit Ethernet (GE) nwere ike ịnye ọnụego mbufe 1000Mbps na netwọk kọmputa. E bipụtara ọkọlọtọ Gigabit Ethernet (nke a maara dị ka ọkọlọtọ IEEE 802.3ab) nke IEEE na-ebipụta na 1999, naanị afọ ole na ole ka ọbịbịa nke ọkọlọtọ Ethernet Fast, ma a naghị eji ya eme ihe ruo mgbe gburugburu 2010. Gigabit Ethernet na-anabata usoro etiti. nke IEEE 803.2 Ethernet na usoro njikwa mgbasa ozi CSMA/CD, nke nwere ike ịrụ ọrụ na ọkara duplex na ọnọdụ duplex zuru ezu. Gigabit Ethernet nwere eriri na ngwaọrụ ndị yiri ya na Fast Ethernet, mana ọ na-agbanwe agbanwe na nke akụ na ụba. Site na mmepe Gigabit Ethernet na-aga n'ihu, ụdịdị dị elu apụtala, dị ka 40G Ethernet na 100G Ethernet. Gigabit Ethernet nwere ụkpụrụ oyi akwa anụ ahụ dị iche iche, dịka 1000BASE-X, 1000BASE-T, na 1000BASE-CX.
