PCI Last modified: Thursday, September 10, 2009
(1) Short for Peripheral Component Interconnect, a local bus standard developed by Intel Corporation. Most modern PCs include a PCI bus in addition to a more general ISA expansion bus. PCI is also used on some versions of the Macintosh computer. PCI is a 64-bit bus, though it is usually implemented as a 32-bit bus. It can run at clock speeds of 33 or 66 MHz. At 32 bits and 33 MHz, it yields a throughput rate of 133 MBps. Although it was developed by Intel, PCI is not tied to any particular family of microprocessors. Also see PCI-X and PCI Express. (2) Short for Payment Card Industry. See related terms PCI compliance (PCI DSS) and Payment Card Industry Security Standards Council (PCI SSC).

Their site contains links to product information, specifications, and membership information. Webopedia's "Did You Know... Understanding PC Buses" Think of a bus as the electronic highway on which data travels within a computer, from one component to another. Basically, it's the conduit used by your entire system to communicate with your CPU. Webopedia's "Did You Know...?"
