How Computers Work

An approachable, hands-on guide to understanding how computers work, from low-level circuits to high-level code. How Computers Really Work is a hands-on guide to the computing ecosystem: everything from circuits to memory and clock signals, machine code, programming languages, operating systems, and the internet. But you won't just read about these concepts, you'll test your knowledge with exercises, and practice what you learn with 41 optional hands-on projects. Build digital circuits, craft a guessing game, convert decimal numbers to binary, examine virtual memory usage, run your own web server, and more. Explore concepts like how to: Think like a software engineer as you use data to describe a real world concept Use Ohm's and Kirchhoff's laws to analyze an electrical circuit Think like a computer as you practice binary addition and execute a program in your mind, step-by-step The book's projects will have you translate your learning into action, as you: Learn how to use a multimeter to measure resistance, current, and voltage Build a half adder to see how logical operations in hardware can be combined to perform useful functions Write a program in assembly language, then examine the resulting machine code Learn to use a debugger, disassemble code, and hack a program to change its behavior without changing the source code Use a port scanner to see which internet ports your computer has open Run your own server and get a solid crash course on how the web works And since a picture is worth a thousand bytes, chapters are filled with detailed diagrams and illustrations to help clarify technical complexities. Requirements: The projects require a variety of hardware - electronics projects need a breadboard, power supply, and various circuit components; software projects are performed on a Raspberry Pi. Appendix B contains a complete list. Even if you skip the projects, the book's major concepts are clearly presented in the main text.

Take a trip through the neural pathways and vital organs of your personal computer with the newest edition of this long-standing bestseller. Glorious full color illustrations make even the most complex subjects easy to understand. Follow PC/Computing senior editor and computer expert Ron White as he shows you the cutting edge technologies, including the Internet, multimedia sound and video, Pentium processors, local bus architecture, Plug and Play, CD-ROM, digital cameras, color printing, and more in new chapters on the hottest, and coolest, PC components.

The updated edition of this award-winning, national bestseller contains information on the latest technologies including multimedia and the Internet. This colorfully illustrated computer anatomy book is filled with basic and insightful information on the workings of a computer and the advanced technology that is making the computer a part of everyday life.

Computers are the most complex machines that have ever been created. This book will tell you how they work and no technical knowledge is required. It explains the operation of a simple, but fully functional, computer in complete detail. Relays, which are explained, are used in the circuitry instead of transistors for simplicity, though transistors are mentioned. Did you ever wonder what a bit, a pixel, a latch, a word (of memory), a data bus, an address bus, a memory, a register, a processor, a timing diagram, a clock (of a processor), an instruction, or machine code is? Though most explanations of how computers work are a lot of analogies or require a background in electrical engineering, this book will tell you precisely what each of them is and how each of them works without requiring any previous knowledge of computers or electronics. This book starts out very simple and gets more complex as it goes along, but everything is explained. The diagram at the end of the Processor' chapter shows just how complex it gets. (To read the whole book for free, go to howcomputers.com, but this book is much easier to read in book form.)

Computers are the most complex machines that have ever been created. This book will tell you how they work, and no technical knowledge is required. It explains in great detail the operation of a simple but functional computer. Although transistors are mentioned, relays are used in the example circuitry for simplicity.
