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?]
