Recovery Glossary > Jumper
Jumper is a metal conductor that closes an electric circuit. Jumper acts
as on/off switch and regulates the hardware configurations. A jumper is
made of two wires and a small piece of metal. The jumper is turned on
when the wires are connected by the metal piece forming a complete circuit.
When the circuit is incomplete the jumper is turned off.
Jumpers are found on motherboards, sound cards, graphics cards, I/O cards,
CD-ROM interface boards, modems, and hard drive controller boards, and
others. Setting a jumper is a very tedious process thus all hardware comes
along with the jumper settings. By placing a jumper plug over a different
set of pins, we can change the motherboard parameters.
