True or false: "Cryptology" and "cryptography" mean the same thing.

False — cryptology is the overarching field; cryptography (designing ciphers) is just one of its two main branches, the other being cryptanalysis.

Cryptology = Cryptography + Cryptanalysis.

Think of it like "medicine" (the full field) vs. "surgery" (one branch). Saying "cryptography" when you mean "cryptology" is a very common mistake, even in professional writing.
