Which layer of the web application architecture includes all physical devices on the client side?

1. Data layer

2. Presentation layer

3. Application layer

4. Business layer

The correct answer is: Presentation layer

The correct answer is the presentation layer because this layer is responsible for how the web application interacts with the user. It includes all the visual elements and user interface components that users interact with directly, such as buttons, forms, and menus, as well as the physical devices on the client side, like computers, tablets, and smartphones. The presentation layer focuses on the end-user experience, conveying the data from the application in a way that is understandable and usable. This layer is critical as it bridges the communication between the user and the underlying application logic, demonstrating how users engage with web applications through their devices. In contrast, the other layers serve different functions. The data layer manages data storage and retrieval, the application layer contains the logic and functionality of the web application, and the business layer often deals with business rules and processes. Therefore, they do not encompass the physical devices through which users interact with the application.
