From Webopedia.com:

"A metal bridge that closes an electrical circuit. Typically, a jumper
consists of a plastic plug that fits over a pair of protruding pins.
Jumpers are sometimes used to configure expansion boards. By placing a
jumper plug over a different set of pins, you can change a board's
parameters."

And from Cisco.com:

"Technical Definition:
Electrical switch consisting of a number of pins and a connector that
can be attached to the pins in a variety of ways. Different circuits are
created by attaching the connector to different pins."

It appears there may be more than one definition on this one ;)
