In the client-server model, what is the role of a web server?

• A. A web server hosts resources and responds to requests from clients (browsers) with resources and status codes.
• B. It computes search results locally on the user’s device.
• C. It routes packets between networks.
• D. It generates random data for testing.

Answer: (A)

In this model, the web server’s job is to store and deliver web content to clients. When a browser requests a page, the server receives that request, finds the requested resource (or runs server-side code to generate it), and sends back the resource along with an HTTP status code like 200 if it’s found and served correctly, or 404 if it isn’t. This back-and-forth lets the browser render the page you see. A server can serve static files like HTML, CSS, and images or dynamic content produced on demand, and it may handle multiple sites or user sessions on one machine. The other activities—computing search results on your device, routing packets between networks, or generating random data for testing—aren’t what a web server does in this setup.
