INTRODUCING HARDWARE
Like millions of other computer users, you have probably used your
desktop or notebook computer to play games, update your blog,
write papers, or build spreadsheets. You can use all these applications
without understanding exactly what goes on inside your computer
case or notebook. But if you are curious to learn more about personal
computers, and if you want to graduate from simply being the end
user of your computer to becoming the master of your machine, then
this information is for you. It is written for anyone who wants to understand
what is happening inside the machine, in order to install new
hardware, diagnose and solve hardware problems, and make purchasing
decisions and then install new hardware. The only assumption
made here is that you are a computer user—that is, you can turn on
your machine, load a software package, and use that software to
accomplish a task. No experience in electronics is assumed.
