What Is A Motherboard?

It is rectangular in shape and is actually a circuit board to which everything important to the running of your computer attaches. It enables all these various components to communicate with each other. It contains the microprocessor socket that is important for defining the type of central processing unit (CPU) used.

It also contains what is called a chipset that connects the CPU to the rest of the system. The BIOS, or basic input/output system also resides in the motherboard. This is what controls the basic functions of the computer. The BIOS chip is what checks all the systems before the computer actually boots up. After that it powers the CPU, which then starts up all the other functions.

The motherboard also contains a real time clock in the form of a battery-operated chip that maintains the time and other functions of the basic system. It contains many other ports or slots that hold various other necessary components of the computer such as video cards, RAM and memory cards and many other things. Without the motherboard, there would be no computer.
