PCI
Peripheral Component Interface/Interconnect. A self-

Most modern PCs include a PCI bus in addition to a more
general ISA expansion bus. PCI is a 32-bit bus, but supports a
64-bit extension for new processors, such as the Pentium II.
It can run at clock speeds of 33 or 66 MHz. At 32 bits and
33 MHz, it yields a throughput rate of 133 megabits per
second. 64-bit implementations running at 66 MHz provide
524 Mbps. See ISA.
