An application programme (also known as a software application, application, or app for short) is a computer programme that is meant to perform a specific task that is not related to the operation of the computer itself, and is typically used by end-users. Examples include word processors, media players, and accounting software. Applications can be packed with the computer and its system software or released separately, and they can be written in proprietary, open-source, or project-based code.
