System board
A system board (also known as the motherboard) is the main printed circuit board found in systems. The
system board allows communication between many of the crucial electronic components of the system,
such as the central processing unit (CPU) and memory, and also provides connectors for other
peripherals. Unlike a backplane, a system board contains significant number of sub-systems such as the
processor expansion cards, and other components.
