RJ-45
<hardware> A {serial} connector which looks very much like a
standard telephone connector, except it houses eight wires
instead of four.
RJ-45s are typically found on {computers} either integrated
into the {mother board} or on a {NIC}. Because they are so
small they are often used on devices such as {terminal
servers} that have many {ports}.
{Ethernet} ({10baseT}) and {Token Ring} sometimes use four
wires of an RJ-45 plug, {100baseVG} uses all eight.
{100BaseTX} uses the same four wires of the RJ-45 connector as
10baseT but the wire must be {category 5} instead of {category
3}.
[Would the cable normally be {shielded twisted pair} or
{unshielded twisted pair}?]
