Elements of Information Theory

Information theory studies the storage and extraction of information. Lossless data compression, lossy data compression and channel coding are some of the fundamental aspects of information theory. Information theory is essentially used in cryptography, which studies the practice of securing communication. It is used in our day-to-day life applications such as ATM cards, computer passwords, website encryptions and electronic commerce. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge. It aims to serve as a resource guide for students and experts alike and contribute to the growth of the discipline.
