What are the main characteristics of a standard controller in application architecture?

A standard controller in application architecture typically has the following characteristics:

• Handling user input — receives and processes events from the user.
• Connection between model and view — retrieves data from the model and passes it to the view, as well as updates the model based on user actions.
• Managing application logic — implements business logic and controls data flow.
• Separating view from data — ensures separation of responsibilities, which simplifies maintenance and testing.

For example, in MVC, the controller receives data from the model, updates the UI, and responds to user actions.
