| Jumpers allow the computer to close an electrical circuit,
allowing the electricity to flow throughout certain sections of the circuit board.
Jumpers consist of a set of small pins that can be covered with a small
plastic box as shown in the illustration to the right. Below the
illustration is a picture of what the jumpers may look like.
In this example, the jumpers have a small tab on top of them
allowing them to be easily removed.
Jumpers are used to configure computer peripherals such as
hard drives,
modems,
sound
cards, and various other components. For example, when installing a new hard drive you
may need to change the jumper settings depending if the hard drive is a
master drive,
slave drive, or
cable select.
Note: When changing the jumpers on any
device, the device and your computer should be turned off
first. In addition whenever inside the computer you should
always be aware of ESD.
