If you have had any prior experience with personal computers, what you might expect to see is some sort of opaque code, called a “prompt,” consisting of phosphorescent green or white letters on a murky background. What you see with Macintosh is the Finder. On a pleasant, light background (you can later change the background to any of a number of patterns, if you like), little pictures called “icons” appear, representing choices available to you.
