It was probably a combination of both. Start by marking “Code: The Hidden Language of Computer Hardware and Software” as Want to Read: Error rating book. It was written from 1987 to 1999, consequently one shouldn't expect any description of newest technologies. In a way, this is a perfect book on the topic. For example, I didn't understand hexadecimal numbers (or indeed what base 4, base 8, etc) numbers meant before I read this book. [Book review] Code: The Hidden Language of Computer Hardware and Software (self.PythonLearners) submitted 4 years ago by jungrothmorton There comes a time in every programmer's journey when they start to wonder "What's actually going on in the computer? 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. With a desire to learn how the high level code (HTML, CSS, JavaScript, etc.) I really enjoyed most of this book. While I did enjoy the later chapters as well, much of it felt so rushed compared to the earlier, slower pace of the book. This is a good book. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in.

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. Similarly I knew a fair amount about how various electrical gates work but not how by pairing multiple gates together you eventually get to RAM, a CPU, etc. At Flatiron School you can change anything, starting a new career in code, data science, or cybersecurity. A very nice introduction into what makes computers tick. 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? 1,077 global ratings | 627 global reviews, Reviewed in the United States on July 24, 2017. The book is very intriguing from the start, beginning with the earliest forms of code (Morse, Braille, etc.). 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 feel like I could clearly explain all of the major concepts to someone else, which I think is a key test of true understanding. Okay, so I'm only 30 pages into this book but I'm hooked. It does at points get pretty deep into the weeds but I really appreciated the author's efforts to provide such an exhaustive dive into how computers w. Wow.

Just finished reading my b-day gift, the 'Code' by Charles Petzold - probably the best engineering book I've ever read. I start getting the math, the logic behind all this technology that has become pretty much the center of my life today. This book is quite incredible. My opinion on this book is really divided : on the one hand I enjoy some chapters, on the other hand I hardly managed to restrain myself from flipping through other chapters. For example, I didn't understand hexadecimal numbers (or indeed what base 4, base 8, etc) numbers meant before I read this boo. Unfortunately, parts of this book seem quite dated (most anything discussing "contemporary" technology, i.e. Petzold then takes a detour to introduce “base” systems, working down from decimal (ten distinct numbers from 0-9 before you have to add another digit to represent “10”) through octal (you only have 8 digits) all the way down to binary where you only have 0s and 1s. Almost makes me want to try again (*almost*). There's a problem loading this menu right now. This book is for us.

Is it comfortable to read this book on Kindle? The book starts off by going straight to the heart of the title - explaining “what is code.” Not, initially, a series of steps describing operations that you’d like a computer to perform, but rather the very simplest codes like morse code — a system for transferring information between people and/or machines. by Microsoft Press, Code: The Hidden Language of Computer Hardware and Software. hello, 5am.). In “Code: The Hidden Language of Computer Hardware and Software,” Petzold takes us from morse code to the early microprocessors of the 70’s and 80’s, providing a deep and satisfying explanation of exactly how computers function. Chapter by chapter, it subtly builds on concepts taught to you in previous chapters. Now I do. 1990s computers) and the final chapter on the graphical revolution goes through way too much, way too fast to be of any use. Just finished reading my b-day gift, the 'Code' by Charles Petzold - probably the best engineering book I've ever read. 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. 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.
