motherboard \moth"er*board`\ n. (Electronics)
The board containing the main circuits of an electronic
device, especially computers. The term is used primarily in
microcomputer literature, where it designates the board
containing the main expansion bus, and usually also the cpu.
On motherboards designed with an expansion bus, often all of
the circuits not contained on an expansion card are on the
motherboard.
[PJC]

(mobo) The main {printed circuit board} in an
electronic device, particularly a computer, which may contain
sockets that accept additional boards ("daughter-boards").

In a {personal computer}, the motherboard contains the {bus},
the {microprocessor}, and {integrated circuits} used for
controlling any built-in {peripherals} such as the {keyboard},
text and graphics display, {serial ports} and {parallel
ports}, {joystick}, and {mouse} {interfaces}.
