Tour the Dock
The Dock is the strip that runs along the bottom of the Mac screen. The Dock is populated with several small images, called icons. Each icon represents a particular component of your Mac, and clicking the icon opens the component.

The icons shown here are typical, but your Mac may display a different arrangement.
