How Computers Work is a fully illustrated guide to the entire world of computing, from the bulky PC on your desktop, to your business laptop, to your ultra portable tablet, to the smartphone you use to catch up on important email and avoid getting lost on the road. It covers all the ways people use their tech, explaining everything from how Windows manages data, to how your browser streams video, to how game makers create 3D worlds. It covers virtually everything related to home networking and the Internet, how viruses and spyware can infiltrate your computer and how firewalls and antivirus programs prevent them, and how Facebook has changed how we stay in touch. This is a book that shows exactly how computers, in all their wondrous incarnations, have infiltrated and improved our lives, from the bulkiest desktop right on down to the most humble of eReaders and smartphones. There is no stone left unturned.
- Lush, full-color illustrations on every page make learning about PC technology fun and easy
- One of the bestselling, longest-running PC books every written, revised!
- Completely updated with many all new illustrations and topics, including smartphones, social media apps and the hottest new game systems
Now in hardcover with lush, coffee table book paper quality!
More than ever before, How Computers Work emphasizes the world of computing. The desktop PC may not be the center of your digital world anymore, but the underlying tech is as pervasive as it's ever been. This new edition completely refocuses its coverage of technology, with a reorganized table of contents, coverage of entirely new topics, and a boatload of revised, rewritten, and re-drawn content to make this book more relevant to a society that does as much of its computing work on a smartphon or tablet as it does on a desktop or tablet. New topics include:
- eReaders (Kindle and Nook)
- Tablets (iPads)
- Advances in Windows
- Mobile operating systems (Android and iOS)
- How flash memory and low power-consumption chips make mobile devices possible
- Touchscreens
- eInk displays
- LED LCD tech
- Fiber Internet
- Skype
- Texting
- Twitter and Facebook
- Multiplayer gaming
- And, of course, all the existing coverage of computer hardware, from processors, to hard disks, to memory, are updated to reflect the current state of their respective techs.
