10Base-T The name commonly
used to refer to the older LAN
technology which preceeded
100Base-T. Similar to 100Base-T,
but running at 10MBit/s.
100Base-T Also known as Fast
Ethernet. Refers to the 100MBit/s
network technology over TUP
cable that is compatible with the
IEEE 802.3u standard. This is a
collision-detect technology, i.e., a
transmission that collides with
another packet already on the
LAN, requires retransmitting the
new packet. Various physical layer
specifications exist, such as
100Base-TX which uses 2 pairs of
Category 5 UTP cable up to 100m
in length.
A
adapter An add-on computer
interface card and circuitry that
provides the physical connection
and data translation between the
host computers’s I/O bus and
external devices or networks.
adapter slot The location where
adapters attach to the backplane.
auto-negotiation Uses a series of
link pulses to encode hardware
capability information, such that a
hub and end node can agree upon
the highest-performing
configuration both are capable of
using.
B
backplane For an I/O bus. The
computer’s circuitry and
connectors to which adapter cards
connect.
C
CAT Category A cable quality
rating. 100Base-T requires CAT-5
cable. See LAN cable.
collision The result of two or
more nodes on an 802.3 network
transmitting at the same time,
producing a garbled transmission.
D
driver A portion of system code
that allows communication
between the operating system and
the network card.
