When one is asked what a jumper is, most of people would answer that it is a clothing design that became famous in the 90s, however, if the word jumper is used in electronics, it already a totally different object. A jumper is actually a short length of conductor that works to close a break in or bypass part of and electrical circuit.
So that they can be utilized, jumpers should be electrically conductive and placed in a non-conductive block of plastic for convenience. Aside from that, this design also helps avoid the risk that an unshielded and unprotected jumper that might accidentally short out during its use.
The magic that these jumpers do is they permit the computer to close an electric circuit which allows the flow of current in specific parts of the circuit board. Jumpers are made up of a set of small pins that can be covered with a small plastic box.
Jumpers, due to this design and make are primarily utilized to configure the settings for computer peripherals such as the motherboard, hard drives, modems, sound cards, and various other components. This means that their typical use is to set up or adjust printed circuit board. For instance, if the motherboard has intrusion detection feature, a jumper can be placed to switch on or switch off this feature.
Even with this great use, the recent trend has been to try to eliminate jumpers entirely from hardware devices by replacing it with auto-configuration or software-controlled configuration. These configurations may be kept in NVRAM, packed by a host processor, or conveyed at system initialization time. In some cases, hot swappable devices may be able to renegotiate their configuration while the system is running. Jumper-less designs, they say are more favourable since they are usually faster and easier to set up and they just need little technical knowledge, and can be adjusted without the need to have physical access to the circuit. However, even with the advantage that jumper-less designs give electronics, jumpers are still used in computers and devices since they are seen as important inventions that have an irreplaceable role in the computing world.
