Can you describe the main characteristics of the MVC architectural pattern?

The architectural pattern MVC (Model-View-Controller) divides the application into three main components:

• Model — responsible for data and business logic. It stores the application's state and manages data.
• View — displays data to the user. It is responsible for the UI and visual presentation.
• Controller — acts as an intermediary between Model and View. It handles user input, updates the model, and changes the view.

This separation simplifies code maintenance and testing, and allows independent development of UI and business logic. In Android, MVC is often implemented through Activity/Fragment as the controller, XML layout as the View, and data classes as the Model.
