Automatic Vs Semi-automatic

OK, so I'm a little new to the world of commercial espresso machines... Can someone explain to me the difference (both in how it works and what it requires from the operator) for a automatic vs. semi-automatic vs. super automatic espresso machines?  I've also heard the term volumetric and am not sure what that refers to either?

 

Thanks!!!
