The PCI bus was introduced in 1993. This is the first bus designed with 32-bit as well as 64-bit capabilities. This four to eight-lane bus provides for fast data transfer and is the obvious choice for Pentium PCs.

The PCI bus supports plug and play or PnP. With a PnP bus and BIOS, a PnP PC can automatically configure its expansion cards without help from you. PCI enjoys a wealth of expansion cards and should support future technology needs for years to come.
