How is a mother board an assential part of a computer?
It connects all the essential parts of a computer together (to
communicate each other). e.g. The mouse and keyboard connect to the
motherboard, the CPU (central processing unit), GPU (Graphics
Processing Unit, also known as the video card), RAM (random access
memory, also known as simply memory), hard drives, DVD/CD drives,
floppy drives are all controlled and interact with each other
through the motherboard.
