Definition of Motherboard

A Motherboard (also called a Main Board, System Board, or Logic Board) is the primary printed circuit board (PCB) of a computer.

It is the central hub that physically connects and allows communication between all the major components of the computer:

  • CPU (Processor) โ€” the brain of the computer
  • RAM (Memory) โ€” temporary storage
  • Storage devices (HDD/SSD)
  • Graphics Card (GPU)
  • Input/Output ports (USB, HDMI, Audio)

Function of the Motherboard

The motherboard acts like a backbone or skeleton of the computer:

  1. Power Distribution: It receives power from the power supply and distributes it to all components.
  2. Data Transfer: It allows components to communicate with each other through bus systems.
  3. Expansion: It has slots (PCIe, RAM slots) for adding new components.
  4. BIOS: Contains the BIOS chip that starts the computer when you press the power button.
