Starts from understandable foundations and builds from there. By saying 'engineering', I mean it. ), but I very much like the book as a whole. Just finished reading my b-day gift, the 'Code' by Charles Petzold - probably the best engineering book I've ever read. You may be able to obtain copies of the hardcover edition from online booksellers listed on my Books page. This book is for us. Vote for your favourite Australian book of 2020! Around this point a number of other key – but rather unrelated – topics are covered like Boolean logic (True/False, AND, OR etc) and number systems (particularly number bases and binary). 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). Goodreads helps you keep track of books you want to read. This project is intended to represent the output of Charles Petzold's "Code" book, realised as a from-the-ground-up electronic simulation. Download for offline reading, highlight, bookmark or take notes while you read Code: The Hidden Language of Computer Hardware and Software. The language of computer hardware and software is not particularly well hidden in my experience. This book basicaly tries to take you from the very basics of how to encode information, such as how binary is used to represent complex information, to understanding how a computer uses information like this to perform intricate operations. When programmers talk about the timeless books that will always be relevant, certain classics always come up: The Mythical Man Month, Structure and Interpretation of Computer Programs, Design Patterns, Refactoring, Code Complete, and others. Starting from workings of an electrical circuit and building up to various logical elements with gradually increasing complexity. It provides a general overview of how computers function. Best bottom-up education ever. The last chapter of the book felt a bit rushed and ended abruptly, but maybe that’s just my wanting the book to go on longer/end at present day. I'll raise my hand with you. petzold-pw5e. Still, the purpose of the book, as I mentioned, is rather to explain the nature of computer codes and hardware at the very low-level. I have been an IT professional for 20 years, but I never knew what the switches on the front panel of the Altar computer were for. A few chapters were tempting to skim For example, Petzold incl. Scott Hanselman says “This book should really be required reading in any CS101 class. The book takes the approach of constructing the computer “on the paper and in our minds” — that's great when you're at least a little familiar with the topic, maybe not so when trying to discover a completely unknown territory (but the author takes great lengths to go through everything step by step — e. g. the various gates, binary subtraction, memory handling, etc.). By saying 'engineering', I mean it. It leads you from the very basics like morse & braille codes to boolean algebra and various numeric systems, from simple tiny electric circuits which bulb the lamp to primitive adding machine (built from relays, hehe), up to history of development and enhancement of computers in the 20th century. Petzold has a great writer's voice and a true talent for making a complicated subject fun to learn. We’d love your help. There are no discussion topics on this book yet. First he explains binary (via morse code and Braille), then he introduces relays and switches, then gates and Boolean logic, and before you know it you're building an electronic counting machine. The book is very intriguing from the start, beginning with the earliest forms of code (Morse, Braille, etc.). Your email address will not be published. I wish I had had this book back when I was taking my first Computer Architecture course in college! Using everyday objects and familiar language systems such as Braille and Morse code, author Charles Petzold weaves an illuminating narrative for anyone who’s ever wondered about the secret inner life of computers and other smart machines. In CODE, they show us the ingenious ways we manipulate language and invent new means of communicating with each other. Welcome back. He continues with a potted history of transistors, microchips, RAM, ROM, character encoding and all sorts of other fun stuff. QUCS - untested; ngSpice - untested; Other? To see what your friends thought of this book. Book Review: Code by Charles Petzold. Petzold spends a long time laying down the basic blocks of electrical engineering before progressing to how bits flow through a circuit board and control things. But without little drawings of trains carrying a cargo of zeros and ones. Refresh and try again. A very nice introduction into what makes computers tick. The beginning is slightly slow, but after the 1/3 mark or so, I couldn't put it down(literally. A couple things don't. As it was, I had to bombard my dad (an electronic engineer) with questions to even make it to the end of some chapters, but then I haven't attended regular maths/science classes since about age 14, so maybe it's not surprising that I'm missing some of the needed background information. How approachable is this book for a someone with no background in math, electronics or computer science, and in general no inclination towards the sciences? Once they have been introduced, a couple of important processors (the Intel 8080 and the Motorola 6800) are examined in detail – a really interesting opportunity to see how the concepts you’ve learnt about have been applied in real life by chip designers. Code: The Hidden Language of Computer Hardware and Software by Charles Petzold 2020-07-08 Leave a comment If you have been reading my book reviews, you know that I like history. In 1949, he wrote the first article about programming a computer to play chess, and in 1952 he designed a mechanical mouse controlled by relays that could learn its way around a maze. This is the book that every computer science … By the end of the book I was itching to buy lots of relays or transformers and make a computer on my living room table! This book should be a pre-requisite for introductory CS classes. With a desire to learn how the high level code (HTML, CSS, JavaScript, etc.) You won’t be disappointed. I can now look around at all the electronics in my house and feel like I know what’s fundamentally going on. October 11th 2000 The more I interact with software, the more those interactions reflect their makers and materials. There's not much programming or CS (apart from some machine code and assembly language examples). Unfortunately, parts of this book seem quite dated (most anything discussing "contemporary" technology, i.e. 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. As it was, I had to bombard my dad (an electronic engineer) with questions to even make it. The majority of the book, however, is great - I had never really delved into logic gates and circuitry, so it was truly eye-opening even if I couldn't fully understand some parts. 1990s computers) and the final chapter on the graphical revolution goes through way too much, way too fast to be of any use. The slow unfolding of how computers are built actually work was extremely fascinating - from simple lightbulb circuits to logic gates to RAM to keyboards and monitors. Information theory is concerned with transmitting digital information in the presence of noise (which usually prevents all the information from getting through) and how to compensate for that. I’m not going to go much further into detail about the rest of the book, except to say that you move towards being able to ‘build’ (conceptually if not actually physically) a fully-working computer gradually, one step at a time. So I've reread this book once more because I felt it was great, yet I could not give it 5/5 before. His story begins with a description of various ways of coding information including Braille, Morse code, and binary code. Much appreciated, thank you! Metaphors and similes are wonderful literary devices but they do nothing but obscure the beauty of technology.”, “In 1948, while working for Bell Telephone Laboratories, he published a paper in the Bell System Technical Journal entitled "A Mathematical Theory of Communication" that not only introduced the word bit in print but established a field of study today known as information theory. This week's BART book of the week is Charles Petzold's Code: The Hidden Language of Computer Hardware and Software, recommended to me by my awesome coworker Dan Tsui. It was a great read and a book that I can recommend to anyone who whishes to understand how computers really works at the most basic level.

Whenever circuits are drawn in the book – from here onwards – they are shown with the wires that have current in them in red, making it very easy to see what is going on. Or if you just want a basic appreciation of one of the most important technologies in human history—the computer. I’d never really understood relays before, but Petzold introduces them with a very good analogy as a ‘labour saving device’ at a telegraph station. 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. 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). Petzold spends a long time laying down the basic blocks of electrical engineering before progressing to how bits flow through. I feel like I've learned a lot by reading this book, especially since we had no relevant computer architecture courses in college. 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. I write on a daily basis actually makes its way through the magical land that is a computer and returns pleasantries to a human being behind the screen, I sat down with this "Code" book. Now I do. In a way, this is a perfect book on the topic. While I did enjoy the later chapters as well, much of it felt so rushed compared to the earlier, slower pace of the book. TODO: Breakout into new pages and review 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? Availability - Hardcover The hardcover edition of this book is out of print. Buy a discounted Paperback of Code online from Australia's leading online bookstore. Unlike other computer science books, the 'Code' teaches how computers work in a nutshell. I regard myself an innocent computer illiterate. The slow unfolding of how computers are built actually work was extremely fascinating - from simple lightbulb circuits to logic gates to RAM to keyboards and monitors. Charles Petzold has been writing about programming for Windows-based operating systems for 24 years. Required fields are marked *. Unfortunately, parts of this book seem quite dated (most anything discussing "contemporary" technology, i.e. Almost makes me want to try again (*almost*). Just a moment while we sign you in to your Goodreads account. The book is very intriguing from the start, beginning with the earliest forms of code (Morse, Braille, etc.). Given how much detail everything is explained in – and how little knowledge is assumed – fitting it into 260 pages is very impressive! In 1984, PC Magazine decided to do a review of printers. For example, I didn't understand hexadecimal numbers (or indeed what base 4, base 8, etc) numbers meant before I read this book. I really enjoyed most of this book.
