Jumper function on Computer

Jumper function on ComputerJumper on a computer is actually a connector (interface) were associated electrical circuitry used to connect or disconnect a circuit. Jumper is also used to set up the electrical board as a computer motherboard.
Let us focus on a Jumper on a computer. Jumper is a computer function is used for setting the computer equipment as necessary. Fortunately we were at this time setting it through the Defense has begun to decrease its use. Therefore, all function settings are now using outo settings making it easier for the user or computer assembler to not much use Jumper.
Jumper on the computer is usually used on motherboards, Disk and Optical Disk, and in some certain VGA card. But because its use more in the motherboard and hard drive, and Optical Disk, then we will only discuss three.Jumper on Motherboard

Jumper on the computer is usually used on motherboards, Disk and Optical Disk, and in some certain VGA card. But because its use more in the motherboard and hard drive, and Optical Disk, then we will only discuss three.Jumper on Motherboard
1. Clear CMOS Jumper
 CMOS jumper is usually located near the CMOS battery. Usually there are 3 feet (pin) on this jumper. Its function is to store and reset the CMOS (an IC program on Motherboard) in the default position (Initial Setting / Factory).Usually the pin to 1 and 2 when connected to a CMOS Jumper the normal position will save any settings that we change the CMOS / BIOS. And if we change the Jumper positions 2 and 3, then the computer will return to the default position.Then what was the default position? Of course, if we do the wrong setting the CMOS / BIOS then if an error occurred that resulted in the computer can not live, then by Clear CMOS computer will return to its original position before we make changes to the CMOS / BIOS.
Similarly, Clear CMOS Jumper can be used if the computer can not we do the change of life due to the hardware, such as processor, but because CMOS / BIOS settings you have stored on computers that are old and not able to read the processor you just replace the Jumper can be you use.
Jumper is also used if you forget the password that you created in the BIOS. By doing Clear CMOS, then the password that you create will disappear by itself.2. Jumper Bus Clock / Bus Speed
 Jumper serves to set your clock to the processor bus. At this time, almost exactly jumper is rarely used. Setting function that had been organized by the jumper now made outo or can be set via the BIOS.
In the picture is one example of a computer Pentium I, which consists of Bus 50, 55, 60, 66 and 75. These buses are on the processor. In every bus that we choose, there are instructions on the use of jumper.
3. Jumper Bus RatioLike the jumper Bus Clock / FSB, this jumper can practically not be reused. Jumper is a multiplication ratio of the processor. For example, processor Pentium I 133 MHz Bus / FSB 66, then the ratio is 2x. Then we do the settings according to the instructions contained in the information in both motherboard and manuals.4. VGA JumperJumper is usually found on the motherboard that provides VGA onboard VGA as well as additional slots. Jumper, usually consisting of 3 legs / pins are used to select whether to use its onboard VGA or VGA slot. Just like-bus clock jumper, jumper has been rarely used and replaced with outo setting, so without doing any setting, VGA will choose which one is used alone.5. Jumper Audio
 Jumper Sound, is the jumper used to enable voice. Jumper is usually composed of 10 pins lined up with the pin number 8 is empty. If you enable audio in front casing, then automatically, in case the socket Audio Audio has enabled this jumper. But if not, prepare a jumper to connect pin number 5 and 6, as well as pin number 9 and 10, otherwise the sound will not come out even if drivers have entered. And these events often occur where the audio can not be heard and the people who do not understand the confusion and thought onboard Sound of Your motherboard died.
6. USB Power Jumper
Have you ever experienced something you can not function USB? or works only on Windows? Not in the DOS (eg by use of a USB keyboard)? Maybe you do not enable USB Power Jumper.
Jumper is on almost all motherboards with USB Socket. Jumper is composed of 3 legs / pins. If not installed, then your USB will not work. When in pairs on one leg, eg pin 1 to pin 2 or pin 2 to pin 3, it will have a different effect. That one will not be able to enable USB in DOS.
7. Jumper Memory / RAMJumper is usually found on the motherboard that has a memory slot 2 types of facilities, such as Motherboard with SDRAM and DDR1 memory slots, or DDR1 to DDR2, it is to choose one memory slot jumper settings required.
Jumper on the hard drive or optical disc (CDRom, DVD, etc.)
 jumper on the hard drive and Optical Disk usually to determine the status of the hard disk or optical disk. Status of the hard drive / optical drive if he will be a master (master) or slave (slave).It is important to be noticed when we did tundem (merging disk to hard disk, or optical disk drive with one cable). When both master status, then they will not be detected by the motherboard. Therefore one must be a master (master) and the other a slave (slave).
In particular motherboard, the status of slave (slave) on a single hard drive (without doing tundem) will not be detected by the motherboard.
Regarding the Master and Slave status information can be found on the label on the hard drive. CMOS jumper is usually located near the CMOS battery. Usually there are 3 feet (pin) on this jumper. Its function is to store and reset the CMOS (an IC program on Motherboard) in the default position (Initial Setting / Factory).Usually the pin to 1 and 2 when connected to a CMOS Jumper the normal position will save any settings that we change the CMOS / BIOS. And if we change the Jumper positions 2 and 3, then the computer will return to the default position.Then what was the default position? Of course, if we do the wrong setting the CMOS / BIOS then if an error occurred that resulted in the computer can not live, then by Clear CMOS computer will return to its original position before we make changes to the CMOS / BIOS.
