A framework is a platform for developing software applications that provide a foundation on which software developers can build programs for a specific platform.Application frameworks became popular with the rise of graphical user interfaces (GUIs), since these tended to promote a standard structure for applications. For example, a framework may include predefined classes and functions that can be used to process input, manage hardware devices, and interact with system software.
