PCI

Peripheral Component Interconnect. The way the various cards talk to the CPU on the motherboard. Most PCI cards are 32 bit. Some high performance SCSI cards are 64 bit, and need special large PCI slots. Multiport Ethernet cards can be 64 bit. For more information on 64 bit PCI see American Megatrends.
