Conventional PCI, often shortened to
PCI, is a
local computer bus for attaching
hardware devices in a
computer. PCI is the
initialism for Peripheral Component Interconnect and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a
processor bus but in a standardized format that is independent of any particular processor's native bus. Devices connected to the PCI bus appear to a bus master to be connected directly to its own bus and are assigned addresses in the processor's address space. It is a
parallel bus, synchronous to a single bus clock.
