Applications software is used to carry out tasks on a computer, such as writing an email, making a poster, doing homework and messaging friends. Some of the applications we might use to do this include a word processor, web browser and graphics software.
Some software, such as word processors, spreadsheets and desktop publishers are called general purpose software because it is possible to carry out lots of different tasks using that application.
Some software is called special purpose software because it performs one specific task. This might include a flight simulator, payroll software or an application for revising maths.
Applications are also used on smartphones to do lots of things, such as social networking, listening to music and messaging.
The word ‘app’ is short for application software. This is a piece of software that allows us to do an everyday task.
