What Is MVC?

MVC stands for model view controller

MVC is a pattern which is used to split or divide the application into three components: models, views, and controllers.

The MVC model defines applications with 3 logic layers, they are

• The business layer (Model )
• The display layer or Presentation layer (View )
• The input control (Controller )

Model :( application data and logic)

The Model is used to represent the application data ,model objects can retrieve data (and store data) from a database.

View: (User Interface)
The View is used to display of the data and you can design your application using view 

Controller: (business logic) 

The Controller is the part of the application that handles user interaction .
Controllers read data from a view, control user input, and send input data to the model...

Note:

Model:database connectivity

View:designing(UI)

Controller:coding(business logic)

Advantages of MVC over ASP.NET

Provides a clean separation of concerns among UI (Presentation layer), model (business layer) and the input control (Controller)

Easy to unit test (testing is easy). 

Improved reusability of model and views. We can have multiple views which can point to the same model and vice versa.
