Definition:
PCI is an abbreviation for Peripheral Component Interconnect, which is a term used to describe a common connection interface for attaching computer peripherals to a PC's motherboard, or main circuit board.
Most often, a PCI slot is used to connect sound and network cards. PCI used to commonly connect video cards, but it has since been replaced by faster connection technologies.
