Can you name the main levels and layers used in clean architecture of software systems?

In clean architecture of software systems, several main layers are distinguished, which ensure separation of responsibilities and independence of components:

• Entities — business logic and rules that do not depend on external factors.
• Use Cases — implementation of specific business processes interacting with entities.
• Interface Adapters — transformation of data between external formats (e.g., UI, databases) and internal models.
• Frameworks and Drivers — external components such as databases, UI, web servers.

Each layer depends only on the more internal layers, which provides flexibility and testability of the system.
