Mainboard

​A mainboard or motherboard is a central board in the computer hardware that provides electrical connection and support to all hardware components in the computer. The mainboard is a Printed Circuit Board (PCB) with electrical wiring in copper tracks that connect all components. This board can be considered the nervous system of computers. It connects the processor with all input and output devices of a computer.
