PCI Slots (Peripheral Component Interconnect)

PCI Slots

The Peripheral Component Interconnect slots, commonly known as the PCI slots, refers to a computer bus. The computer bus is used by the computer to connect to peripheral add-on devices, such as a pci video card, network cards, sound cards, tv tuners, firewire cards, graphics cards and many other types of extension cards.

The PCI expansion slot was introduced by Intel, but can be found in both PC’s and Macs. It displaced previous computer buses (VESA Local Bus and ISA). PCI was then succeeded by the PCI-E or (PCI Express slot), but PCI is still found in most computers because many expansion devices don’t need PCI-E capabilities.

It is also possible to get a PCI card that had more PCI expansion slots on it. This would be helpful for a computer that did not have enough PCI expansion slots for further expansions, although most computers would have an ample amount of slots.

When choosing a computer case, it is a good idea to choose a case that will allow for a bigger enough case so as to have a suitable amount of PCI expansion slots. This can be very useful if you want to add some cards later, such as a wireless card, or some more USB slots, or a TV tuner?
