C. indd 19 11/26/2006 9:48:14 AM All-in-1 / A+ Certification Exm Gde, 6th Ed. / Meyers / 6311-3 CHAPTER The Visible PC 2 In this chapter, you will learn how to • Describe how the PC works • Identify the essential tools of the trade and avoid electrostatic discharge • Identify the different connectors on a typical PC system unit • Identify the major internal and external components of a PC Mastering the craft of a PC technician requires you to learn a lot of details about the many pieces of hardware in the typical PC.

Meyers / 6311-3 Chapter 2: The Visible PC 29 Anti-static wrist straps and mats use tiny resistors—devices that stop or resist the flow of electricity—to prevent anti-static charge from racing through the device. These resistors can fail over time, so it’s always a good idea to read the documentation that comes with your anti-static tools to see how to test those small resistors properly. Any electrical component not in a PC needs to be stored in an anti-static bag, a specially designed bag that sheds whatever static electricity you have when you touch it, thus preventing any damage to components stored within (Figure 2-9).

Understanding the computer at this broad conceptual level—in terms of hardware, OS, and programs—can help you explain things to customers, but good techs have a much more fundamental appreciation and understanding of the complex interplay of all the software and the individual pieces of hardware. In short, techs need to know the processes going on behind the scenes. NOTE The CompTIA A+ certification exams focus on hardware and operating systems; other certifications cover many of the programs in common use today.
