The Internet Book

The Internet Book explains how computers communicate, what the Internet is, how the Internet works, and what services the Internet offers. The sixth edition has fully updated content throughout to include new developments in technology and the rise of AI. The book gently explains key concepts, technologies, and terminology, allowing readers to understand the science behind the Internet, appreciate how the Internet can be used, and discover why people find it so exciting. It explains the origins of the Internet and how rapidly it has grown, as well as the hardware and software that users encounter (e.g. modems, switches, wireless routers, repeaters, and VPN technology). It also provides information on how to avoid scams and exaggerated marketing claims, because understanding how something works enables us to detect false promises and defend against malicious tactics. Designed for readers who do not have a strong technical background, The Internet Book is a clear and comprehensive resource for making sense of the Internet.
