Whats the difference in classes?

I keep reading Z class, Y class, D class - etc and was scratching my head as to what all these classes actually mean and how they differ from one another? - And im guessing price comes into this?!?

I can gather that some classes mean that once you have bought your ticket you cannot change it, upgrade it, anything, your stuck with what you first bought, so im guessing this is the cheapest option?

But what about the others???
