Explain Model-view pattern

Model-view pattern: It is a pattern in which the representation of data (that is, the model) is kept separate from its visualization (that is, the view). These decoupling makes it simpler to change the underlying data representation, or give multiple views, for example. Quite frequently a third element is added to build the Model-View-Controller (abbreviated as MVC) pattern. In MVC pattern, such elements of the system that are able to control or change the data (that is, the model) are too defined separately.
