In a client-server model, which component responds to requests from clients and provides services?

• A. Client
• B. Router
• C. Switch
• D. Server

Answer: (D)

The main idea is that in a client-server setup, services are provided by the server in response to requests from clients. A client initiates an action—asking for data or a service—while the server handles that request, performs the work, and sends back the results. For example, when you load a webpage, your browser asks the web server for the page; the server processes the request, may fetch data from a database, and returns the page content. Routers and switches are network devices that move data around but don’t provide the application services themselves. A client is the requester, not the provider of the service. So the component that responds to requests and provides services is the server.
