PCI-Com
Typical PCI cards used in PCs include: network cards, sound cards, modems, extra ports such as USB or serial, TV tuner cards and disk controllers. The first version of conventional PCI found in consumer desktop computers was a 32-bit bus-Wikipedia using a 33 MHz bus clock and 5 V signaling, although the PCI 1.0 standard provided for a 64-bit-Wikipedia variant as well.
