Computer card "jumper" from the appearance of the watch is inlaid on the motherboard, sound card, hard drives and other equipment small metal stick (jumper column), and set a small clip on the metal rod Tiao Xianjia. Jumper is adjustment device on different electric signals of on-off relationship, in order to adjust to the working state of the equipment, such as determining the motherboard voltage, the drive of the master-slave relationship and so on. When the jumper clamps and set on two jumpers column indicates the column connects these two jumpers, if only on a root or no sleeve, is disconnected. Adjust the jumper is very important, if the wrong, ranging from crashes. Serious can even burn down the equipment, so in the adjustment jumper must carefully read the instructions, check the jumper name, jumper column number and on-off relationship.
The jumper on the motherboard generally include CPU, set the jumper CMOS clean, do not write BIOS jumpers. Among them, the CPU set the jumper is most complex, if the motherboard is old, we must set core voltage, FSB, frequency jumper on the motherboard. According to the motherboard manual and CPU frequency, set the corresponding jumper. Usually case, motherboard corresponding CPU voltage is a group of jumpers, each jumper corresponds to a voltage value, find the appropriate voltage value, in a keycap shorted it, on the choice of the the voltage values. Similarly, find the FSB jumper and frequency jumper, respectively set the appropriate FSB and multiplier. Note, each jumper in can only choose a short jumper.
The jumper here refers to the copper cable, by standard jumper cable and connecting hardware made, jumper cables are two core to eight cores ranging from copper core, connecting hardware for two 6 or 8 bits of the modular plug, or if they have a

A bare head. Some jumpers at one end have module plug the other end has a *-bit module slots, or with **0p wiring plug, mics, or module slot. With the transfer of various link jumper on the wiring frame, can be used as a frame or equipment to connect the cable to use. Module of jumper two RJ*5 connectors, the TIA/EIA***8A needle structure, and flexible plug design, prevent loosening and clamping. Jumper wire length 1 foot (0.**5 m) to **0 feet (1.**5 meters), the most commonly used is the length of 3 feet, 5 feet, 7 inches and *0 feet. The use of modular jumper in the work area, but also can be used as a jumper wiring between. In a small office or home network DIY installation, often mentioned two jumpers. Standard jumper jumper is not this kind of comprehensive wiring, but a kind of special hardware equipment connecting wire, use it in twisted pair will be two PC computers connected directly, or two hub to through the RJ*5 port docking, crossover (commonly known as the cross connect cable, jumper).
