Types of Expansion Slots
PCI Express
The PCI (Peripheral Component Interconnect) Express is the top choice when it comes to expansion slots. The PCI Express communicates with the motherboard, and therefore with the microprocessor, very quickly and efficiently. PCI-Express slots are generally used to connect more advanced video cards.
PCI
This PCI is probably the most common slot found on PCs today. Some PCs have a mix of PCI and PCI Express slots. If you have a choice, always go for PCI Express. PCI expansion slots are used to connect all kinds of devices such as network cards, modems, sound cards, and old graphics cards.
AGP
The AGP (Accelerated Graphics Port) has been specially designed for graphics adapters. Even though some older computers may include the AGP slot, it has mostly been replaced by the PCI Express.
ISA
The oldest type of extension is ISA (Industry Standard Architecture).
