What are jumpers

Jumpers are electrical pins used on motherboards and some devices, such as hard drives, to activate, regulate, or deactivate specific system functions that are not accessible through software. Understand how they can be used for your benefit.

What are jumpers for?

On older motherboards, jumpers were plentiful. Its function as an electric key was to determine the operation of various functions of the board. It was possible, for example, to use a jumper or jumper to limit the power of the processor and, consequently, reduce its speed and heating.

Other jumpero or as it is also known as jumpers reset the function of the BIOS information to factory settings. There were still those responsible for setting the date and time and the system's internal battery control scheme.

The larger boards had a much larger set of jumpers that allowed extensive control over the operation of all the hardware that linked to the motherboard. From the speed of food memories on expansion cards.

If your computer is a few years old, chances are it still contains jumper pools. Please note that several of them can make changes in the delicate operation of the machine.

Do they still exist?

Jumpers are rare to find on new boards (some still own some, used primarily to configure LEDs and the behavior of buttons on the cabinet). With the advancement of technology, especially firmware and BIOS, jumpers simply lost their utility, as it became possible to make all adjustments via software.

Where are they found?

Jumpers are currently falling out of use when it comes to plates. But standard IDE hard drives still have the keys in their set. In HDs, jumpers are used to determine the behavior and hierarchy of the hard drive before the system.

For example, by removing a jumper and positioning it in another space, it determines that the hard disk behaves like a slave in the system, that is, that it is not accused of booting and booting the system. Some disks have jumpers that determine the speed of the read and that can limit the storage space on the disk.

Jumpers are also found on logic boards with specific functions, such as those used in Arduino applications. It should be remembered that Raspberry Pi also brings bridges on your plates.
