100BaseVG | test.arachnode.net

<networking> 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 committee was thus formed and standardised 100BaseVG. The rest is history. (1998-06-30)

Missing definition

First, this is an (English language)
__computing__ dictionary. It includes lots of terms from
related fields such as mathematics and electronics, but if
you're looking for (or want to submit) words from other
subjects or general English words or other languages, try
{(http://wikipedia.org/)}, {(http://onelook.com/)},
{(http://yourdictionary.com/)} or

If you've already searched the dictionary for a computing term
and it's not here then please __don't tell me__. There are,
and always will be, a great many missing terms, no dictionary
is ever complete. I use my limited time to process the
corrections and definitions people have submitted and to add
the {most frequently requested missing terms (missing.html)}.

Try one of the sources mentioned above or
{(http://whatis.techtarget.com/)} or

See also the note on {bad cross-references (dangling.html)}.

What does ... mean? How do I ...? Where can I find ...?

I'm afraid I don't have time to answer personal requests for
definitions, help configure your PC, do your homework, or
explain what that Windoze error message means, etc. so please
__don't ask me__.

How do I submit a definition?

I'm afraid I can't accept any more new definitions at the moment, I
have a huge backlog awaiting processing.

replaced by the first {actual argument} provided by the user
when the {shell script} is run. $2 is replaced by the second
argument, and so on up to $9.

You may have arrived at this entry by following a {URL} like
"http://foldoc.org?$1", which is actually a {template} used to
generate pointers to FOLDOC definitions by replacing "$1" with
the term to be defined, e.g. in a {wiki} {interwiki map}.
