Application software is a program or group of programs designed for end users. These programs are divided into two classes: system software and application software. While system software consists of low-level programs that interact with computers at a basic level, application software resides above system software and includes database programs, word processors, spreadsheets, etc. Application software may be grouped along with system software or published alone.
The term application refers to both the application software and its implementation. A simple, if imperfect, analogy in the world of hardware would be the relationship of an electric light - an application - to an electric power generation plant - the system.
The power plant merely generates electricity, itself not really of any use until harnessed to an application like the electric light which performs a service that the user desires.
Typical examples of software applications are word processors, spreadsheets, and media players.
