What is a mother board ?

In Electronics, a mother board is a board which contains all the other boards.  In computers, the mother board may contain the video card, the network adaptor card, the LAN card and so on.  It will also have a slot for the microprocessor.

The boards which are mounted on the mother board are called the daughter boards.  The daughter boards are mounted on the mother boards using slots.
