Which layer contains code that reads data from the browser and returns the results (e.g., IIS Web Server, Apache Web Server)?

• A. The client or presentation layer
• B. The business logic layer
• C. web-server logic layer
• D. Database layer

Answer: (C)

In a typical web application, the code that reads data from the browser and returns results runs on the server as part of the web-server logic layer. When you submit a form or make a request, the browser sends data via HTTP to the web server (like IIS or Apache). That server-side component reads the incoming data, may hand it to the application’s business logic, and then constructs a response (such as HTML, JSON, or XML) to send back to the browser. The client or presentation layer is the browser itself, which only displays results and collects input. The database layer is where data is stored and retrieved, not where HTTP requests are processed or responses generated. The web-server logic layer is where the initial processing of browser requests happens, coordinating reading the input and delivering the output.
