Questions tagged [model-view-controller]

Model–View–Controller (MVC) is an architectural pattern, introduced in mid 1970-s in PARC into how to compose software interfacing also with user-interactions. For Microsoft ASP.NET MVC, please use [asp.net-mvc] or [asp.net-core-mvc] tag instead. For Spring MVC, please use [spring-mvc] tag instead.

The pattern isolates "domain logic" (the application logic for the user) from the user interface (input and presentation), permitting independent development, testing, portability and maintenance of each (separation of concerns).

The TV screen displays these channels to you (the view). You pressing the buttons on the remote controls affects what you see and how you see it (the controller).
