I am unsure of the technical differences. It’s my understanding that picture one in your post is just a spacer. Picture two would be an adapter if you were changing bolt patterns but could also just be a spacer if you just needed the extra thickness. These are 2” spacer/adapters that are hub centric. The notice there is no “lip” for the hub of the wheel to center and rest on in the pictures in your post.
