ethernet
n : a type of networking technology for local area networks;
originally developed by Xerox Corporation; coaxial cable
carries radio frequency signals between computers at a
rate of 10 megabits per second
From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]:
Ethernet
A {local area network} first described by
Metcalfe & Boggs of {Xerox PARC} in 1976. Specified by {DEC},
{Intel} and {XEROX} (DIX) as {IEEE 802.3} and now recognised
as the industry standard.
Data is broken into {packets} which are transmitted using the
{CSMA/CD} {algorithm} until they arrive at the destination
without colliding with any other The first {contention slot}
after a transmission is reserved for an {acknowledge} packet.
A {node} is either transmitting or receiving at any instant.
The {bandwidth} is about 10 Mbit/s. Disk-Ethernet-Disk
transfer rate with {TCP/IP} is typically 30 kilobyte per
second
Version 2 specifies that {collision} detect of the transceiver
must be activated during the {inter-packet gap} and that when
transmission finishes the differential transmit lines are
driven to 0V (half step). It also specifies some {network
management} functions such as reporting {collisions}, retries
and {deferrals}.
Ethernet cables are classified as "XbaseY", e.g. 10base5,
where X is the data rate in {Mbps}, base" means "{baseband}"
(as opposed to {radio frequency}) and Y is the category of
cabling. The original cable was {10base5} ("full spec"),
others are {10base2} ("thinnet") and {10baseT} ("twisted
pair") which is now (1998) very common. {100baseT} ("{Fast
Ethernet}") is also increasingly common.
