How Computers Really Work: A Hands-On Guide to the Inner Workings of the Machine is an approachable, hands-on guide to understanding how computers work, from low-level circuits to modern software. Coming in 2020! To be published by No Starch Press.
How Computers Really Work: A Hands-On Guide to the Inner Workings of the Machine takes an informal approach to technical topics. Each chapter covers one foundational aspect of computing. Exercises and hands-on activities throughout are designed to help you learn. Exercises mostly involve mental problem solving, while hands-on activities allow you to try various aspects of computing: building a circuit, writing software, and so forth.
You will learn about electrical circuits, learn how to read a circuit diagram, and build a working circuit. You’ll learn how computer hardware like processors, memory, and input/output work and fit together; how low-level machine code runs on a processor, and how to examine the machine code of software running on a computer. You’ll gain an understanding of the differences between programming languages like C and Python; examine operating systems; use tools to explore your local network and the internet, and build a simple web page.
Computing is everywhere, and as our society depends more and more on technology, we need individuals who understand computing broadly. This book will help you construct a mental picture of how computing works, enabling you to then dig deeper into the topics that interest you.
How Computers Really Work: A Hands-On Guide to the Inner Workings of the Machine will be published by No Starch Press.
Matthew Justice is a software engineer. He spent 17 years at Microsoft where he took on various roles, including debugging the Windows kernel, developing automated fixes, and leading a team of engineers responsible for building diagnostic tools and services. He has worked on low-level software (the operating system) and on software far removed from the underlying hardware (such as web applications). Matthew has a degree in electrical engineering. When he's not writing code or building circuits, Matthew enjoys spending time with his family, hiking, reading, arranging music, and playing old video games.
