N-tier architecture is a type of computational architecture that divides an application into multiple layers or tiers, each responsible for a different aspect of the application's functionality. These tiers often include a presentation layer, business logic layer, and data storage layer. The presentation layer provides the user interface, while the business logic layer handles the application's rules and processes. The data storage layer stores and manages the application's data. An N-tier architecture allows for easier maintenance and scalability of the application, as well as improved security and performance.
