When you turn on your computer

When you turn on your PowerBook, the computer looks on the hard disk inside the computer for the system software it uses to start itself up. (A disk that contains the system software is called a startup disk.) When the computer finds the system software, it displays the icon shown and proceeds to start itself up.

When the startup process is complete, the Macintosh desktop appears on the screen. The desktop is a gray pattern with

ma menu bar across the top (containing the names and icons of menus)

man icon near the upper-right corner representing the startup disk

man icon near the lower-right corner representing the Trash

Menu bar

Startup disk icon

Trash icon

When you “wake” your computer from sleep, it does not go through the startup process because it is already on (at a reduced power level). The Macintosh desktop reappears on the screen immediately, looking just the way it did before the computer went to sleep.
