Publishers description: Michael Knee offers a selective guide to the major resources and tools central to the computer industry. A discussion of three commonly used subject classification systems precedes an annotated bibliography of over 500 items.

Everything casual users need to know to get the most out of their new Windows 7 PCs, software, and the Internet, including Facebook, craigslist, Twitter, and Wikipedia.

Why throw away that broken PC? You can fix it - really! Fixing it will save you much needed cash - and keeping your hardware out of the trash is good for the environment, too. Best of all, you don't need to be a technical expert to do most typical computer repairs - and this book proves it. If you've found other computer repair books too complicated (or too cute), you're in the right place. McFedries covers everything you need to know, get, and do, in plain English, with plenty of crystal-clear pictures.

The Complete Idiot's Guide to Buying a Computer covers ALL the necessary considerations to make BEFORE you purchase that computer. What are your computing needs? Mobility? Ease? Portability? Power? Multimedia features? This book leads you through the initial assessment of your computer needs. It then takes you through an industry overview of computers (desktop vs. laptop vs. hand-held) with the inside scoop on the pros and cons of these machines. You will learn about clones and how to decide whether or not to make the clone purchase. You'll also receive information about where to go to make that computer purchase (and where not to go), and what kinds of questions to ask. A tear-out checklist is included to take with you when making your computer investment.

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.
