Expansion slots are located on the motherboard, and openings on the back of the
computer allow the ports on the cards that go in the slots to be accessed.
The picture below shows the SoundBlaster Live sound card, with additional ports
attached to it through an IDE cable.There are several types of expansion slots, including
AGP, PCIe (also known as PCIexpress), PCI, and ISA.
The top card of the SoundBlaster Live sound card plugs into a PCI expansion slot, while
the bottom card sends and receives its data to and from the larger card through an IDE
cable.The smaller card simply needs an empty spot in the case to be mounted to.It does
not need to be placed into an expansion slot on the motherboard.
