CertiGuide to A+ (Core Hardware)  9  Chapter 0111:  Peripheral Devices

I  Introduction to Chapter 0111 1 III  Peripheral Device Interfaces

We will begin this topic by discussing the various methods of transferring data from the PC to the peripheral devices. You will learn about serial communications, parallel communications, Universal Serial Bus (USB), IEEE 1394 (FireWire), infrared, and radio communications.

Continuing from there, you will be shown all of the various ports and connectors that are found on the back of PC. These connector types are defined by the data transfer method they use. You will also learn what devices commonly use these ports and connectors.

Once we have covered the methods of data transfer and the connectors that are used, we discuss the most common types of peripheral devices used with PCs. You will learn about the different types of input devices, such as keyboards and mice.

We will conclude this chapter with a discussion of the most frequently used output devices for PC’s, printers. You will learn about the three main technologies used for generating printed documents; impact printers, inkjet printers, and laser printers.
