Very informative and easy to understand
Format: Paperback
I love how Charles wrote this book, I read it slowly throughout the year and was easily able to digest all the examples and illustrations provided and have got a better and broader understanding of Code, software, hardware, batteries, lightbulbs, history and much more!

Engaging Read for Beginners and Techies Alike
Format: Paperback
An engaging and accessible exploration of how computers really work. The author breaks down complex concepts into simple, relatable explanations, making topics like binary, logic gates, and basic circuits far less intimidating. For newcomers, it’s a great way to build a foundational understanding of computer theory with just a touch of electrical engineering.
As someone with a technical background, I still found it entertaining; the examples and analogies added fresh ways to frame ideas I already knew. It’s the kind of book that can bridge the gap between “I use computers” and “I understand what’s happening under the hood.”
Highly recommended for anyone curious about what makes hardware and software tick, whether you’re starting from scratch or just want a new perspective.
