PCI-X standards are detailed in the following table: PCI-X is generally backward compatible with PCI, meaning that, a PCI-X card can be installed in a PCI slot provided it has the correct voltage keying for the slot and (if inserting in a 32 bit slot) nothing obstructs the overhanging part of the edge connector. PCI-X offers 64-bit (double) bandwidth, revised protocol, and increased maximum signaling frequency (133 MHz). Essentially, PCI-X is a faster version of PCI. PCI-X stands for Peripheral Component Interconnect Extended, a computer bus and expansion card standard designed to supersede PCI. PCI bandwidths are provided in the following table: 32-bit PCI slots and cards are typically provided personal computers, while 64-bit PCI slots and cards are employed in workstations and servers. PCI cards are available in 32-bit and 64-bit bus widths.
With PCI plug and play support, the host system OS automatically configures settings of a PCI card inserted into a mainboard PCI slot. (slot) for attaching peripheral devices and adding functionality to a computer mainboard. PCI stands for Peripheral Component Interconnect, which specifies a computer bus This Data Sheet provides a brief description of each PC card standard. A wide variety of PC cards for attaching external devices or extending functionality to a computer mainboard are available.
