What are some examples of layered architecture in software design?

Layered architecture is a design pattern that separates concerns into different layers. Common examples include the MVC (Model-View-Controller) pattern, where the model handles data, the view manages the user interface, and the controller processes input.

Can you explain how the MVC pattern works in more detail?

Sure! In MVC, the Model represents the data and business logic, the View displays the data to the user, and the Controller handles user input and updates the Model or View accordingly. This separation allows for easier maintenance and scalability.

What are the benefits of using a layered architecture?

The benefits include improved separation of concerns, easier testing and maintenance, and the ability to modify one layer without affecting others. This leads to more organized and manageable code.

Are there any drawbacks to using layered architecture?

Yes, some drawbacks include potential performance overhead due to multiple layers and the complexity of managing interactions between layers. It's important to balance these factors based on the project's needs.
