One of the major replaceable components in computer is the system board, also known as the motherboard. The motherboard is the big green board connected to the computer case. It is the motherboard that holds RAM, processor, and a number of other components in place.

The motherboard is easily the most important part of the computer. Although there are a number of components that a PC cannot function without, it’s the mother-board that ties them all together and turns them into a personal computer.
