Information Science

Drawing concepts from each of the constituent subfields that collectively comprise information science, this book is built around the five "E's" of information: Entropy, Economics, Encryption, Extraction, and Emission. It presents an approach to the field of information science; emphasizes basic principles; and includes examples and applications. From cell phones to Web portals, advances in information and communications technology have thrust society into an information age that is far-reaching, fast-moving, increasingly complex, and yet essential to modern life. Now, renowned scholar and author David Luenberger has produced "Information Science", a text that distills and explains the most important concepts and insights at the core of this ongoing revolution. The book represents the material used in a widely acclaimed course offered at Stanford University. Drawing concepts from each of the constituent subfields that collectively comprise information science, Luenberger builds his book around the five "E's" of information: Entropy, Economics, Encryption, Extraction, and Emission. Each area directly impacts modern information products, services, and technology - everything from word processors to digital cash, database systems to decision making, marketing strategy to spread spectrum communication
