cut-outs, promos, japan and china, etc ???


what do all of these references mean? what is a cut-out or promo? What are the Japan and China pressings or recordings? is there a sound quality difference? are these to be avoided? Any explanation is appreciated. Thanks.

Maybe this is a myth but I heard that white labels/promos are the first pressed, making the white label a flag for one of highest quality copies.
