An expansion slot on the computer is basically add other hardware or peripherals, such as graphics cards, sound cards, and network cards. The expansion slots consist of usually 2 things. The first is the PCI or AGP slot that is on the motherboard itself. The second part is built onto the case. It is pretty much a docking station where you screw the card to the case.

Expansion slots are slots located on the back of the motherboard designed for installing peripheral expansion cards. The number of expansion slots varies from none to 8. Most have more of a range of 3 to 6. The slots connect to the chipset, usually the south bridge chip. The type of expansion slots vary, and sometimes they are mixed.

Expansion cards are peripheral cards that add capabilities to the computer. In some cases, certain peripheral cards are required for basic computer operation. That would be a video card or a disk controller. Expansion cards can also have other abilities such as various types of I/O ports on the back, communications, sound, storage, memory, cryptographic abilities, multimedia connections, home or office security, gaming, and more. Sound and USB are already on most motherboards, and graphics is already on many. If you don't like the existing sound or video that is integrated on the motherboard, or they quit working, you can use the expansion slots to add replacements. Or if you run out of SATA or USB ports, or you want to add upgraded ports (SATA 3, SAS instead of SATA, or USB 3), you can.
