Getting to Know Your Computer's OS
The screen that you see when your computer has finished starting up is called the desktop. Depending on what kind of operating system you have, the desktop will look different, but it generally consists of menus at the bottom, top, and/or sides of the screen, with the rest of the screen containing a desktop background (or wallpaper). The desktop background area can also contain any files, applications, or shortcuts that you want to have quick access to.
