<You are also correct that strictly speaking the words "protocol" and < "algorithm" are probably the same. No, they aren't. In protocols it is essential that there are at least 2 communicating entities running the same protocol (or at least compatible protocols). Each side may be running algorithm(s), but the protocol states what I have to do when the other side sends (or doesn't send) me a message of a certain type. Algorithms frequently have inputs, but these need not come from other algorithms, and are treated accordingly.
