Expansion Slot

Alternatively referred to as a bus slot or expansion port, an expansion slot is an opening located inside a computer on the motherboard or riser board that allows additional boards to be connected to it. For example, if you wanted to install a new video card in the computer you'd purchase a video expansion card and install that card into the compatible expansion slot.
