Chapter 1. Hardware Basics for the Absolute Beginner

IN THIS CHAPTER

  • Get to know your personal computer system

  • Inside the system unit

  • Microprocessors, computer memory, and hard disks

  • Portable storage and CD/DVD drives

  • Understand the startup process

Then we'll examine what exactly happens when you turn on your PC—what we call the startup process.
