A motherboard is the main and the central printed circuit board (PCB) in the modern computers and holds many of the crucial components of the computer system, and provides connectors for other peripheral devices. The motherboard is also known as the main board, system board or the logic board (on Apple computers).It is also sometimes casually shortened to mobo.
Today most of the computer motherboards are designed for IBM-compatible computers, which are currently account for around 90% of global PC sales. A motherboard, like a backplane, provides the electrical connections by which the other components of the system communicate, but unlike a backplane, it also connects the central processing unit and hosts other subsystems and devices.
A typical desktop computer has its microprocessor, main memory, and other essential components connected to the motherboard. Other components such as external storage devices, controllers for video display and sound, and peripheral devices may be attached to the motherboard as plug-in cards or via cables, although in modern computers it is increasingly common to integrate some of these peripheral into the motherboard itself.
An important components of a motherboard is the microprocessor's supporting chipset, which provides the supporting interfaces between the CPU and the various buses and external components. This chipset determines, to an extent, the features and capabilities of the motherboard
