Fidelity

I am trying to learn to ask questions, so I am asking this.Do high fidelity and accuracy mean the same thing to you, and do how do they really rate in your overall enjoyment of music? To me fidelity used to mean real to life until I realized I didnt really know what that meant. I have not heard that many live instruments or live performers. Then, I do not really know what an engineer or artist intended a recording to sound like either. Most of the time I am pretty happy just to listen to a recording and take it as is. I like or I dont. But this question of fidelity puzzles me. If this is an ignorant question I dont mind saying there is a lot I dont know.
