• MOTHERBOARD

The motherboard, also referred to as system board or main board, is the primary circuit board within a personal computer. Many other components connect directly or indirectly to the motherboard. Motherboards usually contain one or more microprocessors, supporting circuitry that usually integrated circuits (ICs) that providing the interface between the CPU memory and input/output peripheral circuits, main memory, and facilities for initial setup of the computer immediately after power-on. In many portable and embedded personal computers, the motherboard houses nearly all of the PC’s core components. Often a motherboard will also contain one or more buses and physical connectors for expansion cards.
