What is the pci express expansion slot?

Answer 1

Its for expanding that computer's ability.

You can add stuff like a tv tuners, sound cards, network card, wireless networking, more ports, video cards, more sata or IDE controllers, etc.

Mind you that for video cards is suggested to use pci express x16, or AGP x8 if you have an old motherboard.

There are also pci express x1, which can do that same thing as the pci slot, but has a much faster transfer rate.

Answer 2

PCI - Peripheral Component Interconnect

Also newer PCI express x16

These are the expansion slots on newer motherboards introduced after AGP was phased out.

Commonly used to support the computers GPU (Graphical processing unit) or the Video Card

Answer 3

PCI Express or PCI-E is a high-speed, serial system bus standard. It is much faster than PCI. It uses the serial standard to prevent problems that cause lower performance like cross-talk and timing skew. PCI-E card can have different length connectors since it uses signal lanes and faster devices use more lanes.

Answer 4

The big PIC-e slot (X16) is used for graphic cards

the small ones are used for other stuff (sound card, TV tuners...)

Answer 5

A PCI slot is used for Graphic cards and other expansions such as PCI based modems.
