Used in the core curriculum at Ball State University’s graduate professional program in Information and Communication Sciences, this textbook is designed for graduate and undergraduate students who do not necessarily have a high level of technical expertise, but need to have some understanding of the technical functions of information and communication technologies to prepare them for working in a corporate environment. See What’s New in the Third Edition: Avoiding complicated equations and the need for calculus gymnastics, this textbook provides non-engineering students with a firm background and a broad understanding of the knowledge necessary to work within the fast-paced and ever-changing communications industry.
