code: the hidden language of computer hardware and software review

Chapter 17 ("Automation"), however, was where I began to feel a bit in over my head. If you know a better one, I want to read it. It was written from 1987 to 1999, consequently one shouldn't expect any description of newest technologies. Reviewed in the United States on January 14, 2020. Full version Code: The Hidden Language of Computer Hardware and Software For Kindle A Microsoft MVP for Client Application Development and a Windows Pioneer Award winner, Petzold is author of the classic, “Code is not like other how-computers-work books. After introducing both codes and electricity, Petzold examines the telegraph - a way to use electricity to transmit encoded information. The route between those two points is the interesting part, and there was some parts that I foudn really illuminating and important. Finally, Petzold introduces the software required to turn a chunk of silicon into Excel, Pac-Man or a website! To handle that, Petzold introduces the idea of a relay — something that takes a small, weak current and uses it to flip a switch in another circuit which can carry a bigger current. Basically, this book designs and builds a basic computer by introducing in each chapter a concept or a technology used inside computers. I read the book together with my 11 years old son and we had a lot of fun. Because computers are so complicated these days, it can be hard to figure out where to start.

Knowledge is empowering! Every single person in tech should read this book. 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. Written in 1999, the book yet actual nowadays (well, there are funny moments regarding computers' capacity and performance, and probably some other stuff but those don't matter much). There's a problem loading this menu right now. This book pretty quickly gets into electricity and basic circuits. The beginning is slightly slow, but after the 1/3 mark or so, I couldn't put it down(literally. I loved it, but felt I needed to go back and re-read stuff that went over my head. Find helpful customer reviews and review ratings for Code: The Hidden Language of Computer Hardware and Software at For that, I believe this is the best book. If not already, it soon will be, a staple of computer science literature. Just finished reading my b-day gift, the 'Code' by Charles Petzold - probably the best engineering book I've ever read. 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. I start getting the math, the logic behind all this technology that has become pretty much the center of my life today. Recommended for anyone who would really like to understand the basic concepts behind computer technology, but doesn't want to go back to graduate school. In my opinion, Code: The Hidden Language of Computer Hardware and Software is a unique book with a conversational tone that leads a general audience of readers through a mix of expository writing, imaginative fictional scenarios, and history, to learn about the inner workings of computer hardware and software. Such a fun and interesting book. Charles doesnt try to explain through high level metaphors (that do a poor job of capturing the truth -- I am frustrated after picking up another apparently interesting physics book only to find it contains no math), rather, he slowly builds on simple examples. If you just want a couple of metaphors to have a sense for how elements of computing work, this is not the book for you. Petzold goes back to the very basics to explain how to build a computer (of sorts) from the ground up. Disabling it will result in some disabled or missing features. It carries you along from the very fundamentals of both codes (like braille) and electric circuits in the telegraph days all the way to the web in a way that even a layperson could understand, with plenty of verbal and diagrammatic explanation. Petzold first introduces the basics of boolean logic and then shows how you can combine that with electricity (starting with simple circuits using a light bulb and switches) to create logic gates. A few chapters were tempting to skim For example, Petzold includes 25 pages on the machine code instructions of an Intel 8080 microprocessor - did we really need all that detail? Reviewed in the United States on November 17, 2019. Whether you want to become a software engineer, or just better understand the technologies that power our world, there’s real value in learning how computers actually work. Interesting for those who want to know the nitty-gritty details of circuits and computers and why they work. Our admissions team is here to help. I can now look around at all the electronics in my house and feel like I know what’s fundamentally going on. It stays at the level that a programmer can relate technically to a 6th grader. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. 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. Unfortunately, parts of this book seem quite dated (most anything discussing "contemporary" technology, i.e. Petzold spends a long time laying down the basic blocks of electrical engineering before progressing to how bits flow through. I really liked the gradual introduction to concepts of increasing complexity where each builds on the one before it. He continues with a potted history of transistors, microchips, RAM, ROM, character encoding and all sorts of other fun stuff. 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. Let us know what’s wrong with this preview of, Published The book is very intriguing from the start, beginning with the earliest forms of code (Morse, Braille, etc.). Definitely one of the greats. This was a wonderful non-fiction read, especially the first 15 or so chapters. It also analyzes reviews to verify trustworthiness. 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. Overall, I loved it and will surely be recommending it to anyone who asks how computers, This book is the perfect depth for novices but also people who are “in tech” and don’t really understand how it all works (like me). The book is very intriguing from the start, beginning with the earliest forms of code (Morse, Braille, etc.). In Morse code, every letter of the alphabet corresponds to a short series of dots and dashes, as you can see in the following table. I wish I had had this book back when I was taking my first Computer Architecture course in college! Starts from understandable foundations and builds from there. I read the Kindle version, and it's fine. This book is quite incredible. Knowledge is empowering!

The route between those two points is the interesting part, and there was some parts that I foudn really illuminating and important. In a way, this is a perfect book on the topic. If you wanted to send messages across the US, you’d need to find a way to make the signal stronger every so many miles. I feel like I've learned a lot by reading this book, especially since we had no relevant computer architecture courses in college. Made in NYC.Change Things, Code: The Hidden Language of Computer Hardware and Software. I purchased this book to challenge myself, but I honestly never thought I'd understand the material so well. Or if you're just interested in tech. What a ride! He has been programming with Windows since first obtaining a beta Windows 1.0 SDK in the spring of 1985, and he wrote the very first magazine article on Windows programming in 1986. It provides a general overview of how computers function. If you’re willing to take the time to work through the 380 pages, you’ll never quite think about a computer in the same way again! Great intro into the world of computing. And has this, uh, unprecedented year gotten completely in the way of... What do flashlights, the British invasion, black cats, and seesaws have to do with computers? While Petzold does assume the reader is starting from scratch, I think it would be easier to follow later on if you had some background in computers/technology. Refresh and try again. In the spirit of starting from the basics, Petzold also provides an introduction to electricity by introducing “the anatomy of a flashlight.” In doing so, he explains how electrons are moved through a circuit by a voltage, explaining what voltage, current, and resistance really mean.
