The computer motherboard is unarguably the most important component of a computer system. It is a flat and rectangular circuit board where all other components of the computer system are connected. Therefore without the motherboard any other computer peripherals are irrelevant.

It also link all other components that make the computer to function as a systematic arrangement. In the computer hardware market, a complete knock down buyer is presented noting less than a motherboard with connecting wires and chips.

Most computer components have their root in the motherboard, A typical motherboard may contain different slots for attaching video graphic adapter,sound cards, it also contains ports for monitor, keyboards, mouse speakers and removable devices.

The computer mother board also contains sockets that accommodate the CPU, but they are built to support different CPU’s. It also houses the RAM sockets and the links to the hard drive.

The motherboard can also be referred to as the heart of the computer, because, major operations of the computer like the booting systems start from the board.

The basic input/output or BIOS chips are resident in the motherboard, therefore during system start up the BIOS in conjunction with the operating system will check the internal system for possible errors during system start up.
