Which of the following expansion slots is characterized by having an x16 speed?

A.    CNR
B.    PCI
C.    PCIe
D.    AGP

Answer: C
The PCIe xXX is the amount of lanes the slot has. so x16 has 16 lanes, x8 has 8 lanes and so on.
The physical slot on x4, x8, and x16 are all the same.
If it says 2 PCIe x16 slots it means that there are 2 slots on the board that are capable of 16 lanes. If it says 2 PCIe X16 (and then in brackets says x16, x4 or x8, x8) it means when you have 1 slot being used it uses all 16 lanes for that 1 slot. But if you plug multiple things into the PCIe slots (most common 2 GPU's) it will divide the lanes between the cards. So that (x16, x4) you will have the first GPU running with 16 lanes, and the second GPU running with 4 lanes.
