Chapter.2, “The System Unit,”
explained the inner workings of a computer inside
the mysterious box known as the system unit. In this chapter, you'll look at how
data moves into and out of that system unit—via input and output devices.
Different kinds of computers accept input from different sources. For example, a
desktop PC might have a keyboard and mouse, whereas a tablet PC or smartphone
might have a touch screen and some built-in buttons. Output can include messages
and data that appear on the monitor screen, a hard-copy printout, and audio cues
or prompts the computer might generate, such as a warning beep or the playback
of your favorite song. Storage devices hold information for later use; they vary by
capacity, interface, and the medium used to store the files.
