100BaseVG is a 100 Mbit/s Ethernet standard specified to run over four pairs of category 3 UTP wires (known as voice grade, hence the "VG"). It is also called 100VG-AnyLAN because it was defined to carry both Ethernet and token ring frame types. Ethernet (this name comes from the physical concept of ether) is a frame based computer networking technology for local area networks (LANs). ...
Category 3 can refer to either: Category 3 cable used for carrying data Category 3 hurricanes on the Saffir-Simpson Hurricane Scale. ...
UTP can mean: in genetics, uridine 5-triphosphate in telecommunications, unshielded twisted pair cabling the USS Thomas Paine the United Tasmania Party Universiti Teknologi Petronas This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ...
Token-Ring local area network (LAN) technology, developed and promoted by IBM in the early 1980s and standardised as IEEE 802. ...
100BaseVG was originally proposed by Hewlett-Packard, ratified by the ISO in 1995 and was practically extinct by 1998. The Hewlett-Packard Company (NYSE: HPQ), commonly known as HP, is a very large, global company headquartered in Palo Alto, California, United States. ...
ISO has many meanings: Iso is the stem of the Latin transliteration of the Greek word ίÏÎ¿Ï (Ãsos, meaning equal). The iso- prefix in English derives from this and means equality or similarity. ...

1998 is a common year starting on Thursday of the Gregorian calendar, and was designated the International Year of the Ocean. ...
100BaseVG started in the IEEE 802.3 committee as Fast Ethernet. One faction wanted to keep CSMA/CD in order to keep it pure Ethernet, even though the collision domain problem limited the distances to one tenth that of 10BASE-T. Another faction wanted to change to a polling architecture from the hub (they called it "demand priority") in order to maintain the 10baseT distances, and also to make it a deterministic protocol. The first faction argued that, since IEEE 802.3 was the Ethernet committee, it was not the place to develop a different protocol. Thus, the IEEE 802.12 committee was formed and standardized 100BaseVG. IEEE 802. ...
Fast Ethernet is a collective term for a number of Ethernet standards that carry traffic at the nominal rate of 100 Mbit/s, against the original Ethernet speed of 10 Mbit/s. ...
In computer networking, Carrier Sense Multiple Access With Collision Detection (CSMA/CD) is a network control protocol in which (a) a carrier sensing scheme is used and (b) a transmitting data station that detects another signal while transmitting a frame, stops transmitting that frame, transmits a jam signal, and then...
