Different Amp classes

[sokrman14]

If someone could educate me briefly on what the different types of classes of amps are I would appreciate it. I have heard of AB amps and class D amps, but arent sure of what that means. Also are there more classes than just those two? Any help would be great so I know what I am looking for when I change to separates.
