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.
