The Model-View-Controller (MVC) architecture is a software design pattern that separates an application into three interconnected components. This separation promotes organized, testable, and scalable code—especially in web development.

MVC breakdown:

• Model: Handles data and business logic. It retrieves data from a database and processes it.
• View: The user interface. It displays data provided by the model and sends user input to the controller.
• Controller: Interprets user input and instructs the model and view to take action.

How it works:

1. The user interacts with the view (e.g., clicks a button).
2. The controller processes the input and calls the appropriate model.
3. The model updates the data and notifies the view to reflect changes.

Advantages of MVC:

• Clear separation of concerns.
• Easier to test and maintain.
• Supports parallel development (e.g., one developer works on UI, another on logic).

Common MVC frameworks:

• Django (Python)
• Ruby on Rails
• Laravel (PHP)
• ASP.NET MVC
• Spring MVC (Java)

MVC is a timeless pattern and a solid foundation for learning structured development. It helps keep code clean and maintainable, especially in large applications.
