The CPU is the brain of the computer, while the mainboard is the backbone. This article will introduce mainboard types and the block diagram of the mainboard.
1. Function of the mainboard
The mainboard is the primary circuit that connects all the components and peripherals in a computer. It’s also referred to as the mainboard or system board.
2. Types of Desktop mainboard
AT (Advanced Technology) mainboard: This is an older mainboard that is typically used with the Intel 486 and Intel Pentium II CPUs. It has a small size.
