Can you name the main levels that make up the concept of clean architecture?

Clean architecture typically consists of several main layers that separate business logic from implementation details:

1. Entities — business objects and rules that do not depend on external systems.
2. Use Cases — specific business rules and application logic that implement tasks.
3. Interface Adapters — convert data between internal and external layers, such as controllers, repositories.
4. Frameworks and Drivers — external components like databases, web frameworks, UI.

These layers are organized so that dependencies point inward, which facilitates testing and maintaining the code.
