Peripheral Component Interconnect

aliases:

• PCI

The most common expansion bus type, with three generations, PCIe x16 being the fastest and typically used for GPUs.

PCI was developed to replace the obsolete Industry Standard Architecture (ISA) and (Video Electronic Standards Association) 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.
• Is 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 Mbps or run at 66 MHz and transfer data at 266 Mbps.
