PCI

Stands for "Peripheral Component Interconnect." It is a PC bus designed by Intel, and used in both IBM-compatible and Apple computers. Most add-on cards such as a 3DFX Voodoo 3 card or a SCSI card use a PCI connection. These slots are found in the back of your computer and are about 3.5" long and about 0.5" high. You should make sure you have at least one available PCI slot before you go buy that hot new 3D card you absolutely need.
