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 not typically found on

computers or normal serial equipment, but because they are

so small they are often used on devices such as terminalservers 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 category3.
