Communication Technology Update and Fundamentals, now in its 18th edition, has set the standard as the single best resource for students and professionals looking to brush up on how communication technologies have developed, grown, and converged, as well as what's in store for the future. The book covers the fundamentals of communication technology in five sections that explain the communication technology ecosystem, its history, theories, structure, and regulations. Separate chapters then explore the background, recent developments, and current status of two dozen technologies in electronic mass media, computers, consumer electronics, telephony, and networking. The chapters are written by experts who provide a snapshot of an individual field. Together, these updates provide a broad overview of these industries and examine the role communication technologies play in our everyday lives. In addition to substantial updates to each chapter, the 18th edition includes first-ever chapters on surveillance and remote working and learning, plus updated user data in every chapter; an overview of industry structure, including recent and proposed mergers and acquisitions; and sidebars about people who have made a lasting contribution to communication technologies.
