This Chapter expands on the discussion in Chapter 10, "Expansion Buses," by defining and exploring some of the PC's most popular add-ons. Printers are the second most common output devices (after monitors), and modems have moved from the exotic to the essential with the rise of the Internet. These two peripheral devices are connected to the computer through cabling and connectors, which are also covered in this chapter.
Because the devices discussed in this chapter are connected to the computer by means of expansion buses, it is suggested that you review Chapter 10. Specifically, you should be familiar with the different types of expansion buses and how to configure IRQs and addresses.
