There's no guarantee that the two messages won't experience the same corruption - so 100% is overstating it. And, AIUI, certain check codes are more effective than simply repeating the original. For example, SECDED memory with just a few extra bits encodes enough info to correct a single bit error (and detect double-bit errors). James
