Question

The MVC design pattern is often used when creating websites. In this case, how is the user's communication with the server most often realized (orange arrows in the picture)?

Select one:

a. The user communicates from a client application (such as a Web browser) using the HTTP protocol. When a request is created with a specific URL, a controller is selected, which, after loading the data into the model, passes the model to the view and sends it in response.

b. The user communicates using the TCP / UDP protocol. The controller takes over the application call and selects the view that will handle the request. The view reads the data and sends a response to the user.

c. The user calls the controller via a client application (such as a Web browser or mobile application). The controller finds out from the model which view should be used, fills it with data and sends it in response to the user.

d. The user calls the controller via a client application (such as a Web browser). The controller passes the request to the model and the view. The view then sends a response to the user using the library from the model.
