Information Science

To study these principles is to learn how English text, music, and pictures can be compressed, how it is possible to construct a digital signature that cannot simply be copied, how beautiful photographs can be sent from distant planets with a tiny battery, how communication networks expand, and how producers of information products can make a profit under difficult market conditions. The book contains vivid examples, illustrations, exercises, and points of historic interest, all of which bring to life the analytic methods presented: presents a unified approach to the field of information science; emphasizes basic principles; includes a wide range of examples and applications; helps students develop important new skills; and suggests exercises with solutions in an instructor's manual. Professors: A supplementary "Solutions Manual" is available for this book. It is restricted to teachers using the text in courses
