Any software program which allows a computer to be used for a specific task. Application programs include for word processing (such as WordPerfect), creating spreadsheets (Excel), laying out pages for publication (QuarkXPress), manipulating digital photographs (Adobe Photoshop), or drawing illustrations (Macromedia FreeHand), among many others. An application program often comes with a wide variety of "extras," such as plug-ins, system extensions, tutorials, and other elements that add functionality to the basic program. This collection of extras (including the documentation needed to learn how to operate the program) is known as an application package.
