The motherboard is the foundation of a computer. It allocates power and allows
communication to and between the [CPU](CPU_architecture.md), memory,
[harddisk](What_are_disks.md) and all other hardware components.

It is a printed circuit board and is always the largest board within the
computer chassis.
