Adinary Nuance

A motherboard is the central board inside a computer. It is not the same as a circuit board in general, because many devices have circuit boards, but not every board is a motherboard. It is also different from a CPU: the CPU is the processor chip, while the motherboard is the board that holds and connects parts.
