Bus Architecture that combines the capabilities of MCA and EISA with the ability to send video instructions at speeds to match the microprocessor.
A PC expansion bus that was developed by Intel specifically for Plug and Play implementations. There have been at least two major revisions to the PCI bus. This bus supports either 32 or 64-bit operation at speeds ranging from 20 to 66 MHz. One unique aspect of this bus is that it does not contain a separate address bus. Address information is sent on the first clock cycle with subsequent clock cycles containing the data. Under PCI 2.1 specifications, a single PCI slot runs 64-bits at 66 MHz, all other slots operate at 64-bits/33 MHz or 32-bits/66 MHz.
a local bus standard developed by Intel Corporation. PCI is a 64-bit bus, though it is usually implemented as a 32-bit bus. It can run at clock speeds of 33 or 66 MHz.
