**Motherboard**
If you've ever taken the case off of a computer, you've seen the one piece of equipment that ties everything together - the motherboard. A motherboard allows all the parts of your computer to receive power and communicate with one another.
Motherboards have come a long way in the last twenty years. The first motherboards held very few actual components. The first IBM PC motherboard had only a processor and card slots. Users plugged components like floppy drive controllers and memory into the slots.
Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades. In this article, we'll look at the general components of a motherboard. Then, we'll closely examine five points that dramatically affect what a computer can do.
A motherboard by itself is useless, but a computer has to have one to operate. The motherboard's main job is to hold the computer's microprocessor chip and let everything else connect to it. Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port.
The shape and layout of a motherboard is called the form factor. The form factor affects where individual components go and the shape of the computer's case. There are several specific form factors that most PC motherboards use so that they can all fit in standard cases.
The form factor is just one of the many standards that apply to motherboards. Some of the other standards include:

The form factor is just one of the many standards that apply to motherboards. Some of the other standards include:
- The socket for the microprocessor determines what kind of (CPU) the motherboard uses.
- The chipset is part of the motherboard's logic system and is usually made of two parts - the northbridge and the southbridge. These two "bridges" connect the CPU to other parts of the computer.
- The (BIOS) chip controls the most basic functions of the computer and performs a self-test every time you turn it on. Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating.
- The real time clock chip is a battery operated chip that maintains basic settings and the system time.
