PCI (Peripheral Component Interface)
an improved bus for PCcompatible computers, introduced by Intel in 1992. PCI is faster than EISA and has been expanded to 64 bits to meet the needs of the Pentium processor. PCI-bus computers can use a bus interface unit on the motherboard to connect to EISA or ISA cards, so that the same motherboard has both PCI and ISA slots.
