So technically a rib roast is sort of a generic term for any roast cut from the rib primal. A "prime rib roast" is a more specific 6-7 bones (from ribs 6-12 or 13) section of the entire primal rib. Where it gets even more confusing is the "prime" in prime ribroast has nothing to do with the USDA Prime grade you get with some beef. You can get a "prime rib roast" of USDA choice/select or prime, or ungraded.

A standing rib roast is just a bone-in roast preparation of a rib roast. Usually presented with the cleaned bone end pointed up.
