What Is a Jumper in Computing?

A fascinating world exists within the confines of a computer case. It’s a world teeming with tiny components, each playing a crucial role in the overall operation of the system. Among these, the computer jumper stands out. Despite its small size, this component plays a pivotal role in the functioning of the hardware and software aspects of a computer.

What is a jumper in computer hardware?

In the realm of computer hardware, a jumper is a tiny plastic and metal plug that creates an electrical connection between two points. This connection acts as a switch, controlling certain aspects of the computer’s operation. Typically found on the motherboard, jumpers can alter settings such as the CPU voltage or reset the BIOS password.

The function of a jumper hinges on its placement. It connects two pins out of a set, with the number of pins varying from three to several dozen, depending on the requirement. The position of the jumper determines the setting that it controls.

What is a jumper in computer programming?

In computer programming, a “jumper” takes on a different role. It refers to an instruction that causes the program to leap, or “jump,” to another part of the code. This is not a physical component but a piece of code embedded within the program. The use of jumpers in programming facilitates the efficient execution of code by allowing it to skip unnecessary sections, thereby improving performance.

Identifying a jumper on the motherboard

Recognizing a jumper on a motherboard requires a keen eye due to its diminutive size. Jumpers are typically located near the battery or along the edges of the motherboard. They consist of a pair or a group of pins protruding from the board, with the jumper itself – a small plastic cap containing a metal bridge – connecting two of the pins. The motherboard manual provides a detailed diagram of the jumper locations and their corresponding functions.

What are jumperless systems?

Modern technology has led to the emergence of jumperless systems. In such systems, changes that were traditionally made via jumpers are now handled through software interfaces in the BIOS or UEFI. This advancement simplifies the process of altering system settings and eliminates the risk of damaging hardware components.


Whether it’s a tiny plug on a motherboard or a line of code in a program, the term “jumper” refers to a component that makes a significant contribution to the functioning of a computer. By learning what a jumper is and how it operates, we can better appreciate the complexity and the fascinating intricacies of the world that lies within our computer cases.
