CHAPTER 18
Input/Output
In this chapter, you will learn how to
Explain how to support common input/output ports
Identify certain common input/output devices on a PC
Describe how certain specialty input/output devices work on a PC
In Chapter 3, “The Visible PC,” you learned how to recognize and connect a number of common devices and the ports they use. Because these devices and their ports sometimes fail, it is important that you learn how they work and how to troubleshoot them when problems arise. This chapter reviews some of the major types of input ports, discusses a number of common and not-so-common input/output (I/O) devices, and deals with some of the troubleshooting issues you may encounter with I/O devices and their ports.
The CompTIA A+ certification exam domains split computer I/O devices into three groups: common, multimedia, and specialty. Common I/O devices, such as keyboards and mice, are found on virtually every PC.
