First we will start with the motherboard it is the heart of the computer it ties all the components together and lets each component send and receive messages from each other. The easiest way to identify a motherboard is all the different slots there will be slots for the memory which would be the most obvious identifier these are long thin compartments only a mm or so wide. Noting these will help to quickly conclude that what you are looking at is a motherboard as none of the other components will have these slots.
