Managing Open Windows

In the olden days of computers, when you ran a program, that program took over the entire screen. To
use a different program, you had to exit the one you were in and then start the other program. That
program, in turn, hogged the entire screen. With WindowsXP, you can pretty much run as many
programs as you want. Instead of hogging the entire screen, each program occupies only a window on
the screen. That’s where the name Windows comes from in Microsoft Windows. In Figure 2-2, for
example, I currently have two open windows on the screen: one titled My Computer, the other titled
Windows Media Player. You can see the title (name) of each window in its upper-left corner.
