Some are highly visible, in laptops, tablets, cell phones, and smart watches. But most are invisible, like those in appliances, cars, medical equipment, transportation systems, power grids, and weapons. We never see the myriad computers that quietly collect, share, and sometimes leak personal data about us. Governments and companies increasingly use computers to monitor what we do. Social networks and advertisers know more about us than we should be comfortable with. Criminals have all-too-easy access to our data. Do we truly understand the power of computers in our world? In this updated edition of Understanding the Digital World , Brian Kernighan explains how computer hardware, software, and networks work. Topics include how computers are built and how they compute; what programming is; how the Internet and web operate; and how all of these affect security, privacy, property, and other important social, political, and economic issues. Kernighan touches on fundamental ideas from computer science and some of the inherent limitations of computers, and new sections in the book explore Python programming, big data, machine learning, and much more. Numerous color illustrations, notes on sources for further exploration, and a glossary explaining technical terms and buzzwords are included. Understanding the Digital World is a must-read for readers of all backgrounds who want to know more about computers and communications. Review: Mind-bending but enlightening - I picked up Understanding the Digital World to get a clearer picture of how the internet, data, and technology really work. Some parts were straightforward and quite illuminating. But other sections… wow. It dives into concepts so abstract that at times I just threw up my hands and thought, “It does not compute!” That said, the book ultimately helps you connect the dots and understand the massive, complex digital ecosystem we live in. It’s a challenging read, but worth it for anyone trying to make sense of our tech-driven world. Review: Excellent introduction to computing - For the past couple of years I've been co-teaching a course that draws both engineers and policy-minded students. For the policy-minded students, many of whom have little acquaintance with computers except as users, this book is excellent. The engineers may not learn much new technically, but this book can still broaden their perspective on the field. The first edition was very good and the second edition improves on it.
