Review quote

"It's critical for persons in all areas of business to have some familiarity with the rapidly evolving world of communications. This book was the basis for a course at Lucent Technologies focused on introducing financial managers to this area. The material was very successful, got very positive reviews all around, and will continue to be a key part of our education of non-technical managers in important infrastructure markets, technologies, and capabilities."-Donald K. Peterson, Chief Financial Officer, Lucent Technologiesshow more

Back cover copy

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.show more
