A motherboard is the central or main circuit board making up a multifaceted electronic system, such as a modern computer. It is also recognized as a mainboard, baseboard, system board, or, on Apple computers, a logic board, and is from time to time abbreviated as mobo.[1]
Most after-market motherboards formed today are designed for so-called IBM-compatible computers, which hold over 96% of the personal computer market today.[2] Motherboards for IBM-compatible computers are specifically enclosed in the PC motherboard article.
The basic purpose of the motherboard, like a backplane, is to supply the electrical and logical connections by which the other components of the system communicate.
A archetypal desktop computer is built with the microprocessor, main memory, and other essential components on the motherboard. Other components such as external storage, controllers for video display and sound, and peripheral devices are typically attached to the motherboard via edge connectors and cables, although in modern computers it is increasingly common to integrate these “peripherals” into the motherboard.
