What are real the life examples of layered architecture?

Layered architecture is commonly found in various real-life applications. For instance, in web applications, the presentation layer (UI), business logic layer (server-side processing), and data access layer (database interaction) are distinct. Similarly, in enterprise software, systems like Customer Relationship Management (CRM) platforms separate user interfaces, application logic, and data management to enhance maintainability and scalability. Additionally, mobile applications often employ a layered approach, isolating user interfaces, business logic, and network communication to streamline development and updates.
