Motherboard
A motherboard, also known as mainboard (MoBo) or systemboard, is the central or primary circuit board making up a complex electronic system, such as a computer.
A typical computer is built with the microprocessor, main memory, and other basic components on the motherboard. Other components of the computer such as external storage, control circuits for video display and sound, and peripheral devices are typically attached to the motherboard via connectors or cables of some sort.

Mainboards
All electrical devices have a board where logical processing begins when the device is powered on. In general, this would be identified as the mainboard. Usually, only devices where substantial, varied, and complex calculations occur have their mainboards referred to as motherboards. Computers, game consoles, and PDAs will usually be associated with the term motherboard, while TVs, home theater receivers, and home appliances normally will not.
Components of computer motherboards
Universal
All motherboards have either these core components or some alternative for providing their functionality.
Expansion slots
The number and type of expansion slots are determined by the motherboard manufacturer subject to limitations of the ISA
Optional peripheral interfaces
These components are entirely optional, although market economics has made some of them ubiquitous in modern computers.
