Motherboard

Every PC has one printed circuit card in it that serves as its foundation (logically and often mechanically as well) this circuit board is commonly called a motherboard.

The motherboard is the backbone of the computer system.

The Standard formats are ATX and Micro ATX. This naming system is part of an agreement between the Manufacturers.

The purpose of the motherboard is to connect all the components including Memory chips, of the computer together using system buses (the printed circuits) these buses convey the information to and from devices and plug in cards and disk drives.

The common generic name for these circuits is the motherboard chipset.
