Jumper

The Jumper is a small metal connector that acts 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, toggled on or off. The other jumpers are plastic sleeves with metal linings in which two metallic prongs are connected with the help of lining.

When the sleeve is applied in this, the connection is on, and when it is removed, the connection is turned off. You will get to see jumpers in computer hardware and other types of electronic devices.

A motherboard has many jumpers that enable different types of components. Hard drives also have a lot of jumpers that 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, 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, you will see a row of jumpers in a garage door remote. These jumpers must match with the setting of the 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, a remote typically changes the frequency to which it communicates. This allows you to use different frequencies on different devices.

By the way, altering jumpers seems like a very high-tech process, but it is very easy in reality.

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

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