Answer:
Broadly defined, a code is a system in which one thing (e.g., a word, number, symbol) stands for something else (e.g., another word, symbol, or number; an idea or meme). Although we will talk about codes in more general terms, in this text, we are most interested in the role codes play in message processing. To distinguish between codes in the general sense and codes that have a first-order role in the creation of understanding between people, we will call the latter as communicative codes.
