information according to Shannon is equal to entropy. 8 http://communicationtheory.org/shannon-and-weaver-model-of-communication/ Says what? In which channel? To whom? With what effect? Who? 10 Redundancy- is the opposite of information. Something that is redundant adds little‚ if any‚ information to a message. Redundancy is important because it helps combat noise in a communication system‚ e.g. in repeating the message. A code- is a language or other set of symbols or signs that can be used to
