INFORMATION THEORIES Meaning and
Definition
-
Information theory is a branch of mathematical communication theory that deals with the quantification, storage, and transmission of information. It provides a framework for understanding and analyzing the limits and inefficiencies of various communication systems.
At its core, information theory aims to measure and describe the amount of information contained in a message or data set. It seeks to answer questions such as how much information can be transmitted through a communication channel, how to compress data to minimize storage space, and how to ensure reliable transmission in the presence of noise or interference.
The main concept in information theory is entropy, which refers to the average amount of uncertainty or randomness in a message. Entropy measures the amount of information needed to encode or transmit a message and provides a definition of information in terms of probabilities.
Information theory employs mathematical tools and methods from probability theory and statistics to analyze and optimize communication systems. It has applications in various fields, including telecommunications, computer science, cryptography, data compression, and genetic coding.
Overall, information theory provides a theoretical foundation for understanding how information is created, transmitted, and processed. By quantifying and analyzing the properties and limitations of communication systems, it enables the development of efficient and reliable communication technologies.

Etymology of INFORMATION THEORIES
The word "information" originates from the Latin word "informatio", which means "concept" or "idea". In the Middle Ages, it was used in the sense of "instruction" or "teaching". The term "theory" comes from the Greek word "theoria", meaning "contemplation" or "speculation".
The phrase "information theory" was coined by Claude Shannon in 1948 when he published his groundbreaking paper titled "A Mathematical Theory of Communication". Shannon's work focused on quantifying information and developing a theory to quantify the capacity of communication channels.
The fusion of "information" and "theory" in "information theory" reflects Shannon's intention to establish a mathematical framework for understanding the fundamental properties and limits of communication. The term has since been widely adopted and is now used to refer to the study of the mathematical and computational aspects of information.
