On your computer monitor, the background behind all the windows, menus, and dialog boxes is referred to as the desktop. It is supposed to represent a desk, which explains why it is called a desktop. 


  When you open a window on your desktop, several pictures will be displayed. These pictures are called icons, and they can represent a file, directory, or action for your computer. Placing the mouse pointer on the icon and double-clicking will allow you to access the information the icon controls.
Program icon
        A program icon represents a software package.
File icon
        A file icon represents a place to store information created by a program or for use with that program. 
Folder icon
        A folder icon represents a group of programs and files that you want to locate together.

Task Bar

The task bar is a strip that is usually at the bottom of your screen. From it you can launch programs, view the time clock, open the Start menu, and see icons for inactive windows (windows that are not highlighted). 

Locate the task bar and icons on your desktop. 

Display properties
You can change the appearance of your desktop by right mouse clicking on the desktop, and then point to Properties on the popup menu.

To see more settings, click the tabs at the top of the Display Properties dialog box.

Open the Display Properties dialog box, click on the Appearance tab and the Background tab. Practice changing the appearance and background of your desktop.
