Today in class we discussed expansion slots. There are five types of expansion slots:
1) PCI
2) AGP
3) PCIe
4) AMR
5) CNR

The PCI slots and adapters are made in 3.3V and 5V versions.

The AGP slots were known for video card use

The PCIe are 7 widths x1, x2, x4, x8, x12, x16, and x32, but the most common are the x1, x4, and x16 and the least common is x8. but that is still more common than the x2, x12, x32.

The AMR was once common in a lot of the Intel motherboards, but this is starting to get pushed off the motherboard by newer technologies.

The CNR slots, these slots are one of the technologies that are replacing the AMRs.
