A motherboard is the central or primary printed circuit board (PCB) creation up a multifaceted electronic system, such as a modern computer. It is also known as a mainboard, baseboard, system board, planar board, or, on Apple computers, a logic board, and is now and then abbreviated carelessly as mobo. Most motherboards shaped today are intended for so-called IBM-compatible computers, which detained over 96% of the global personal computer market in 2005.Motherboards for IBM-compatible computers are specially covered in the PC motherboard article.
A motherboard, like a backplane, provides the electrical relations by which the other mechanism of the system converse, but unlike a backplane also contains the central dispensation unit and other subsystems such as real time clock, and some tangential interfaces.
A typical desktop computer is built with the microprocessor, main memory, and other necessary components on the motherboard. Other components such as external storage, controllers for video display and sound, and peripheral devices are classically attached to the motherboard via edge connectors and cables, although in modern computers it is more and more common to integrate these "peripherals" into the motherboard.
