Icons are little pictures that say exactly what they mean. They're logos and illustrations wrapped into one that show computer users the who, what, where, and mouse click. I've learned that basic icons can be personalized along with the appearance of someone's screen desktop or could be used in the process of web design. They're usually very small like 16 x 16 pixels or 24 x 24 pixels, and certain types can appear in the toolbar and sidebar menus in many word processing and digital imaging programs.

I believe icons are an easy way to memorize certain functions of your program. They visually describe the functions which sometimes can be simplier than remembering the right hot keys on your keyboard or finding the words or commands on the regular drop-down menu. However, you should use a manual or your program's help file to make sure the icons do what they look like they should do. For example, the Save and Save As commands sometimes have icons that are identical but might have different colors or sizes. Before you click on one, a popup word in a yellow or white box (also known as a "tool tip") may appear to let you know what this icon does.
