What is the function of a computer jumper?

Answer 1

To configure a hardware device. For example, IDE hard drives have a set of pins near the power cable and controller cable connectors. There is a jumper that can be set to tell the device that it is a master or slave drive on the port. Some old SCSI hard drives had a jumper for designating the number of the device on the SCSI bus. SCSI can have up to 8 devices on one bus, including the controller. So technically it only supports 7 devices. Many motherboards support processors of different speeds. These motherboards will have jumpers that can be set to tell it how fast the processor operates.

Answer 2

Jumpers for a PC hard drive are next to the power connector. Mostly in between the power connector and the data cable connector. These are used for setting up Master/Slave settings and also to limit capacity of the HDD seen by PC BIOS on some older hard disks. Usually settings which are selected by jumper setting to various locations are printed on the hard disk information sticker.

Jumpers are small pieces of plastic with a metal tab in them. They are used for connecting two pins together and forming a circuit, usually to indicate some setting. Most computers use the BIOS to control all the settings in a computer, so there is only one jumper, used to put the BIOS into a recovery mode.

Answer 4

A "jumper" in computing is a small piece of metal surrounded by plastic approximately 1millimeter by 3 millimeters which is used to "jump" or short a connection between two places on a circuit board. They are used most commonly for setup on motherboards and disk drives.

Answer 5

A jumper, depicted above, is a connector that connects between two pins on a motherboard. They are made of plastic and contain a piece of metal to carry electricity. Their purpose is to configure the motherboard or to bypass something. On older systems, jumpers were used to set the CPU and bus speed.

Answer 6

we have three types of jumper in a system and they are:(1)cable select jumper(2)slave jumper(3)master jumper

Answer 7

a jumper is used to "jump" or short a connection between two places on a circuit board
