code: the hidden language of computer hardware and software review

Very close to my ideal book. I am teaching a class and using this as the text. And Petzold helps me to walk inside an electrical circuit, a telephone, a telegraph, an adding machine, a computer, and to understand the basics behind the design, of what is going on inside. Surprisingly interesting. With a fair background in Computer Science, I found parts of this book very boring but it was a good read overall. Although Morse code has absolutely nothing to do with computers, becoming familiar with the nature inner structures of computer hardware and software. 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. I can now look around at all the electronics in my house and feel like I know what’s fundamentally going on. He introduces the classic Von Neuman architecture that underlies most computers, explains how semiconductors work and then introduces two of the early, classic microprocessors from the late 1970’s - the Intel 8080 and the Motorola 6800. In a way, this is a perfect book on the topic. I did need to read it more slowly than I do most other books, but the upshot was that I felt confident in my comprehension of the material before moving on to the next chapter. With a transistor, a small current on one of their three terminals allows you to switch a bigger current between the other two terminals — just like a relay, but in a much smaller and more efficient package. With a desire to learn how the high level code (HTML, CSS, JavaScript, etc.) 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! code. It provides a general overview of how computers function. 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.). Chapter by chapter, it subtly builds on concepts taught to you in previous chapters. I didn't think it was going to work but the car started right up! The route between those two points is the interesting part, and there was some parts that I foudn really illuminating and important. 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. This book should be a pre-requisite for introductory CS classes. The Hidden Language of Computer Hardware and Software. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. He even introduces some worked examples. Charles is an MVP for Client Application Development and the author of several other books including Code: The Hidden Language of Computer Hardware and Software. The route between those two points is the interesting part, and there was some parts that I foudn really illuminating and important. And that's coming from someone who already thought they "sorta" understood how it worked. 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. Petzold goes back to the very basics to explain how to build a computer (of sorts) from the ground up. By saying 'engineering', I mean it. I can now look around at all the electronics in my house and feel like I know what’s fundamentally going on. The beginning is slightly slow, but after the 1/3 mark or so, I couldn't put it down(literally. It also analyzes reviews to verify trustworthiness. Full version Code: The Hidden Language of Computer Hardware and Software For Kindle I wish I had had this book back when I was taking my first Computer Architecture course in college! Understanding what's going on at the core of your code can never hurt, and this is the most interesting way you could ever learn about it. I start getting the math, the logic behind all this technology that has become pretty much the center of my life today. Very helpful for me, an adult who didn't grow up with computers, to understand how they actually work. If you like books and love to build cool products, we may be looking for you. This book is quite incredible. The book is very intriguing from the start, beginning with the earliest forms of code (Morse, Braille, etc.). 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. Welcome back. Read honest and unbiased product reviews … Overall, I loved it and will surely be recommending it to anyone who asks how computers work. Now I do. Definitely one of the greats. Is it comfortable to read this book on Kindle? Such a fun and interesting book. Prime members enjoy FREE Delivery and exclusive access to music, movies, TV shows, original audio series, and Kindle books. Almost makes me want to try again (*almost*). If not already, it soon will be, a staple of computer science literature. I regard myself an innocent computer illiterate. Interesting for those who want to know the nitty-gritty details of circuits and computers and why they work. Great intro into the world of computing. For example, I didn't understand hexadecimal numbers (or indeed what base 4, base 8, etc) numbers meant before I read this book. I noticed that many of the reviews are written by folks who have some sort of technical background (e.g., engineers, IT professionals, or even just taking college-level classes in computer science). 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). Find the perfect course for you across our in-person and online programs designed to power your career change. 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. 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. It also discusses some relevant historical moments as a typical professor in a typical lecture would do and ends with a broad overview of personal computers as they were in 1999. 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. 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. It's at a pretty good intro level and many of the students seem to like it a lot. And that’s something we’ll see a lot more of as the book progresses since most computers also use a binary code (with 1s and 0s) to represent information and instructions. So I wanted to encourage people like me, who have no experience whatsoever in CS, to give this book a try! From here, he shows how to create the capacity to add and subtract using just logic gates and then introduces oscillators (that change between two stable states frequently) and flip-flops - a kind of gate that adds memory to a system.
