Explanation
Three-tier architecture is a well-established software design pattern that divides an application into three distinct functional layers: the Presentation tier (the user interface layer that users interact with), the Application tier (the business logic/processing layer that handles rules and computations), and the Data tier (responsible for data storage and retrieval). This separation improves scalability, maintainability, and security. The other options describe unrelated concepts: development stages, network stack components, or deployment environments - none of which define the three-tier client-server architecture model.
