It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution. Review: Makes your concept clear - This should be first book for computer science student and engineers. Review: It fills the knowledge gap... - It's a lovely book. It fills the knowledge gap about how a computer actually works and understands our logic. It gives us the explanation for why we code the way we do! ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #14,558 in Books ( See Top 100 in Books ) #3 in C & C++ Programming #6 in Introductory & Beginning Programming #7 in Software Architecture | | Customer Reviews | 4.7 out of 5 stars 979 Reviews | ## Images ![Code: The Hidden Language of Computer Hardware and Software - Image 1](https://m.media-amazon.com/images/I/61Hc-9h+-XL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Makes your concept clear *by A***A on 26 December 2025* This should be first book for computer science student and engineers. ### ⭐⭐⭐⭐⭐ It fills the knowledge gap... *by P***M on 3 February 2025* It's a lovely book. It fills the knowledge gap about how a computer actually works and understands our logic. It gives us the explanation for why we code the way we do! ### ⭐⭐⭐⭐⭐ I'm on page 216 *by J***M on 4 August 2024* Which is just shy of half way through. Phenomenal, incredible book. Petzold, what a guy. What a service to self taught devs like me. I think an early foundational book in any self taught devs library - one that's looking to give themselves a computer science education, anyway. ## Frequently Bought Together - Code: The Hidden Language of Computer Hardware and Software - Operating Systems: Three Easy Pieces - The Elements of Computing Systems, second edition: Building a Modern Computer from First Principles --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/405223234-code-the-hidden-language-of-computer-hardware-and-software](https://www.desertcart.nz/products/405223234-code-the-hidden-language-of-computer-hardware-and-software) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-26*
