Can you explain how the key components of the MVC architectural pattern interact?

In the architectural pattern MVC (Model-View-Controller), the key components interact as follows:

• Model — responsible for the data and business logic of the application. It does not know about the view and controller.
• View — displays data to the user. It receives information from the model and updates when changes occur.
• Controller — acts as an intermediary between the model and the view. It handles user input, updates the model, and updates the view if necessary.

Interaction example:

1. The user interacts with the View (for example, presses a button).
2. The Controller receives the event, processes it, and changes data in the Model.
3. The Model updates its state and notifies the View of the changes.
4. The View updates the display based on the new data.

Thus, MVC separates responsibilities, simplifying support and development of the application.
