Information Theory

July 17th Fact-of-the-Day

Information Theory is a branch of statistical communication theory where physical observation information or the information content of messages is studied relative to the problem of transmitting the information between two or more places. It is important to understand that 'information' has nothing to do with the meaning, correctness or usefulness of an observation or message within the context of information theory, but instead has to do with the randomness or uncertainty of an observation or message. In addition to being a branch of statistical communication theory, information theory also has emerged as a branch of probability theory, because uncertainty can be modeled mathematically in terms of probabilities. Many key results from that modeling have profound mathematical significance entirely apart from their communication theory applications. ©2005 Martek, International. All rights reserved.
