100BaseFX

{Fast Ethernet} over {optical fibre}.

(1998-03-23)

100BaseT

Any of several {Fast Ethernet} 100 {MBps}
{CSMA/CD} standards for {twisted pair} cables, including:
100BaseTx (100 Mbps over two-pair {Cat5} or better cable),
100BaseT4 (100 Mbps over four-pair {Cat3} or better cable),
100BaseT2 (in committee; 100 Mbps over two-pair Cat3 or better
cable). All are standards (or planned standards) under {IEEE}
{802.3}.

100BaseTX

The predominant form of {Fast Ethernet}.
100BaseTX runs over two pairs of wires in {category 5} cable.

100BaseVG

A 100 {MBps} {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.

100BaseVG was originally proposed by {Hewlett-Packard},
ratified by the {ISO} in 1995 and practically extinct by 1998.

100BaseVG started in the IEEE 802.3u 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 {10baseT}.
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 CSMA/CD crowd said, "This is
802.3 -- the Ethernet committee. If you guys want to make a
different protocol, form your own committee". The IEEE 802.12
