42 Chapter 2: Working on the Desktop
What’s on the desktop?
Just as a desk’s large flat surface is its work space, the Macintosh
“desktop” is the work space on your computer. The desktop
metaphor gives you a familiar way of thinking about how to use
the PowerBook.
Aside from the field of gray that represents the “surface” of your
work space, the Macintosh desktop has icons, windows, and
menus.
n
Icons represent containers.
n
Windows let you view what’s inside the containers.
n
Menus list actions that you can apply to selected containers
or their contents.
Icons represent containers
Icons can contain other icons, or they can contain information.
For example, the startup hard disk icon contains the System
Folder icon. The System Folder icon contains the programs (also
represented by icons) that in turn contain the information the
PowerBook needs to start itself up and work properly.
