In communication, a code word is an element of a standardized code or protocol. Each code word is assembled in accordance with the specific rules of the code and assigned a unique meaning. Code words are typically used for reasons of reliability, clarity, brevity, or secrecy.
Background
Coding Theory is the branch of mathematics that covers source codes and channel codes.
A channel code contains redundancy to allow more reliable communication in the presence of noise. This redundancy means that only a limited set of signals is allowed: this set is the code.
A source code is used to compress words (or phrases or data) by mapping common words into shorter words.
Procedure words are used for voice communication on noisy channels.
