FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A motherboard is the main printed circuit board (PCB) in a computer. The motherboard is a computer’s central communications backbone connectivity point, through which all components and external peripherals connect. Motherboards can be found in virtually all computers, especially desktop and laptop PCs.

Detailed explanation-2: -The motherboard is the computer’s main circuit board. It’s a thin plate that holds the CPU, memory, connectors for the hard drive and optical drives, expansion cards to control the video and audio, and connections to your computer’s ports (such as USB ports).

Detailed explanation-3: -It’s called a motherboard because it is the main circuit board in the computer, and it can be extended by plugging other circuit boards into it. These extensions are called daughter boards. Wikipedia suggests that historically a “mainboard” was not extensible in this way, hence the need for different terminology.
