It's a category error to those well-versed in cryptography, like "explain the difference between mergesort and recursion" - two unrelated concepts. (Whereas "explain the difference between quicksort and mergesort" is an interesting question.)
Your answer also does not sufficiently differentiate between e.g. key agreement (DH), message authentication ("signing"; HMAC), symmetric encryption (AES), or asymmetric encryption and signing (RSA).
