This book presents the underlying engineering behind information technology that is transforming our economic and social systems so dramatically. It addresses a need that has arisen from the impact information technology is making on all professions, technical and non-technical. Understanding of information science and engineering, underlying high performance computing and communications is relevant for students from all disciplines today. Covering a broad range of technologies and assuming no formal engineering or computer science background, this book prepares readers to become active practitioners and leaders in the on-going information revolution. Using technology to educate the reader about the technology, the accompanying CD contains links to a set of Java-based virtual laboratory experiments. The integration of Java and Java Script-based applets with the book greatly enhances the presentation of material by allowing the reader to experience the underlying components of information technology in actin, rather than merely in description.Cyganski, David is the author of 'Information Technology Inside and Outside', published 2000 under ISBN 9780130114969 and ISBN 0130114960.
