@maxwalker2003. I get the general definitions, but from the standpoint of a computer analysis I'm wondering whether each is defined by a particular change in point advantage/disadvantage.

Hmm, seems like that link isn't working. Well, if you can copypaste it, a page where the difference between all those is explained

@ripachu, thank you so much. Exactly what I was looking for!
Now, one more question: anywhere specific I should go to have an analysis of a game played here at chess.com further explained? I have a couple of games that I ran through the analysis and I really don't understand the analysis that's shown for a couple of specific moves.
I've started using analysis to look at my games and was wondering whether there are specific definitions for each of these terms. In particular, what's meant by "inaccuracy"? But for that matter, what makes a move "Excellent" or merely "Good" too?
