What is PCI Express? Easily explained

With PCI Express you can connect internal devices to the mainboard in computers. In this practical tip, we explain where PCIe is used and what it is exactly.

PCI Express - what is it?

• PCI-Express stands for "Peripheral Component Interconnect Express", which means "express connection of peripheral components".
• Simply put, PCI-Express (PCIe) is a type of connection between the chipset of the main processor of a computer and various plug-in cards, such as sound and graphics cards.
• So you plug the appropriate hardware into the PCIe port so that your computer can recognize it.
• PCIe replaces its predecessors PCI and AGP with a significantly faster transfer rate.
• Modern graphics cards primarily work with PCIe.

If your old graphics card stops working, you can bake it instead of throwing it away. You can read more about this in our next practical tip.
