Was developed to replace the obsolete ISA and VESA bus standards. PCI:
~Is processor independent, meaning the CPU and PCI bus can process concurrently
~Supports plug and play, meaning installed devices are detected and configured automatically
~Most commonly used by devices such as sound cards, modems, network cards, and storage device controllers
~Can run at 33 MHz and transfer data at 133 MB/s or run at 66 MHz and transfer data at 266 MB/s
