What Is It?

Actually a square plastic board with chips, printed circuits and expansion slots on it.

What Does It Do?

This board sits inside of your computer case, it is what many of your other computer devices plug into. It is called “main” or “mother” board because most of your computer’s devices (CPU, Memory Chips, Video Card and Modem) plug directly into it.

Devices such as the ones mentioned above plug directly unto the motherboard via expansion slots (see white slots in picture, just above).
