Motherboard is a complex printed circuit board (PCB), that is the central part of many electronic systems, particularly the computers. They are alternately known as mainboard, system board, or logic board (Apple Computers). A motherboard is a platform that offers electrical connections through which other components of a computer communicate, and it also has the central processing unit (CPU), generally referred to as the brain of computer. Motherboards are also present in mobile phones, clocks, stop watches, etc. Motherboards include a lot of essential components of a computer such as microprocessor, main memory, microprocessor’s supporting chipset that provides interfaces between CPU and other external components. The devices revolutionized the way computer systems were designed. The earlier versions were confusing and time consuming. Few things that a motherboard nowadays include are:
Sockets for microprocessors
Slots where main memory (Random Access Memory) is installed
A chipset that forms an interface between CPU, main memory and peripheral buses
BIOS (Basic input/output system)
Expansion card slots, etc
