It is truly a book on code, and not just "how to code" or "what to do with code" but "what on earth is code" and where did it come from. It explains computers and computing in more usable terms than more technical books on the same subject because it focuses on history and scope rather than technical depth. For a reader like me, who asked every teacher from elementary school through college "why do we count to 10" and clung to the best answer of "it's arbitrary - it's just how it's always been done" until reading this book (and who struggled to convert binary to base ten), this book was gold. Pure gold. ### ⭐⭐⭐⭐⭐ however after some reading I've got to love it very quickly *by A***N on June 17, 2016* I'm an electronics engineer so basically I was not expecting to find much new stuff of this book when I first browsed the table of contents, however after some reading I've got to love it very quickly. Yeah, chances are that most of the devices described along the pages are familiar to many people, specially for those with education in engineering, but the way this book takes you from one to the next is as natural that new relationships start to be apparent right away and then, you finally got it !!. This book is a very nice mix of technical and historical, it will use your interest in electronics to tell you the whole story from the Morse code to the microprocessor. As I read I learned more about the many difficulties that our peers from the past had to deal with to solve their problems and, ultimately, create the technology of today. ### ⭐⭐⭐⭐⭐ Very good read *by Y***S on July 24, 2017* Okay, so I'm only 30 pages into this book but I'm hooked. I started taking evening IT classes to get into a different career and ran into some issues in my A+ certification went they kept using volts, amperes and other terms that I only had a vague idea of what they meant. This book gave me a more solid understanding of these terms, so much so I saved a friend $85 dollars that he was about spent on a starter for his car. I saw immediately that the cable wire attached to the battery was missing a few inches of electrical tape, leaving the copper exposed. This book taught me that electricity does not ran very well through air, so we went to Auto Zone and bought some electrical tape to cover the exposed areas, making sure enough electricity is getting to the battery. I didn't think it was going to work but the car started right up! For a noob like me this was a big deal. This author created a strong interest in me for chemistry, which would of been real helpful years ago but oh well. I enjoyed his intro into Morse code and Brail as it felt he was conditioning readers to grasp idea how computers received and process information. Brail was very interesting as he pointed out how certain markers will alert a blind person to cease interpreting letters and switch over to numbers, than another nullifier to switch back to letters. --- ## 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.us/products/91282975-code-the-hidden-language-of-computer-hardware-and-software-by](https://www.desertcart.us/products/91282975-code-the-hidden-language-of-computer-hardware-and-software-by) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-30*
