The Jumper is a small metal connector that works as an on / off switch. Multiple jumpers are often used by combining a hardware device to configure settings .

Some jumpers are encased in a plastic switch, which can be toggled on or off. The other jumpers are plastic sleeves with metal linings in which two metallic prongs are connected by lining.

In this, when the sleeve is applied, then the connection is on and when it is removed, the connection is closed. You will get to see jumpers in computer hardware as well as other types of electronic devices.

A motherboard has many jumpers that are used to enable different types of components. Hard drives also have a lot of jumpers which enable and disable many features.

For example, spread spectrum clocking (SSC) can be enabled from a jumper setting, while PHY or “ physical layer ” mode can be enabled from another .

These settings may be required in the hard drive , along with some specific types of hardware to make them work.

You can also see the use of jumpers in common household electronics, such as remote controls.

At the same time, in a garage door remote you will see a row of jumpers. These jumpers must match with the setting of garage door receiver so that it can work properly.

Ceiling fan remotes include jumpers that can be customized to match the settings of a specific fan.

To modify the jumper settings of a remote, a remote typically changes the frequency to which it communicates. This allows you to use different frequencies in different devices.

By the way, even though altering jumpers appears to be a very high-tech process, in reality it is very easy.

Remotes, for example, typically have jumpers in it, right next to the battery so that it can be easily switched on or off.

In this, you just have to pay attention that you modify the jumper settings correctly. This is because if you modify the wrong jumpers then your device may not work as well.
