It consists of three major components: the Basic Input/Output System (BIOS) chip, the Central Processing Unit (CPU), and the system buses.The initial settings for operating the system at power up are stored on the BIOS chip. These settings are backed up by a small battery. This battery is usually round and approximately the size of a quarter. The BIOS contains settings for the size and location of the boot device, the I/O specifications for peripherals connected to the Peripheral Component Interface (PCI) bus, and other settings that must be maintained when the computer is powered down.The CPU is the brain of the computer. It does all the processing for all the programs in the system. The CPU also acts as a traffic cop by relaying information to and between individual system components.Every component in the computer must be able to communicate with the CPU through the motherboard. This is done via a collection of copper or gold tracings attached to the motherboard. These tiny wires are called buses. These buses are explained in more detail below A motherboard is the most critical part of a computer system.
