Different types and colors of jumpers, with two individual black jumper pins on the left for scale.

In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of computers. The process of setting a jumper is often called strapping.[citation needed]

A strapping option is a hardware configuration setting usually sensed only during power-up or bootstrapping of a device (or even a single chip).[1]
