Expansion slot
The expansion slots in a PC consist of a few types, made for different purposes. The slots are used to install component cards that perform specialized functions, from networking to graphics processing and more. The most widely used slot type is still the long-time mainstay called PCI, though there are newer slots replacing the PCI card slots post-haste. The new common slot type is called PCI-Express or PCI-E. It is the kid brother of traditional PCI, and much faster for the add-in cards you put in your desktop. AGP is another common expansion form factor, typically used by graphics cards.
