-- (Peripheral Component Interconnect)
An Intel designed
bus that facilitates quick communication between a peripheral
and the computer's CPU. PCI buses let users install additional
peripherals to a system and support plug-and-play capabilities.
PCI is the major form of expandability available for the computer.
Many kinds of PCI cards can be purchased, such as Video, TV
/ Radio tuner cards, and sound cards. Sometimes a PCI card will
come with another addition as is the case with a DVD drive and
it's PCI decoder card. The dominant uses or PCI cards are for
either video cards or for modem / NIC cards. AGP (another expansion
card architecture) is rapidly gaining ground as the dominant
form for video cards.
