Ans.PCI-X stands for PCI Extended.

The PCI-X spec essentially doubled the bus width from 32 bits to 64 bits, thereby

increasing bandwidth. The PCI's basic clock rate is increased to 66MHz with a 133MHz

variety on the high end, providing another boost to the bandwidth and bringing it up

to 1GB/s (at 133MHz).

Having said this PCI-X still suffers from the problem of Shared bus topology and

also the faster a bus runs, the more sensitive it becomes to background noise. For this

reason manufacturing standards for high-speed buses are exceptionally strict and

therefore expensive. The PCI-x slot is physically longer that a PCI Slot.
