MVC is a framework methodology that divides an application's implementation into three component roles: models, views, and controllers.

"Models" in a MVC based application are the components of the application that are responsible for maintaining state.

"Views" in a MVC based application are the components responsible for displaying the application's user interface.

"Controllers" in a MVC based application are the components responsible for handling end user interaction, manipulating the model, and ultimately choosing a view to render to display UI.
