Which device is known for receiving data requests from clients?

The server is known for receiving data requests from clients because it is designed to process requests and deliver resources or services to client devices over a network. When a client, such as a computer or a mobile device, sends a request for data—such as accessing a website or retrieving a file—the server handles that request by sending back the appropriate data. Servers can host various types of applications, databases, and files and provide services like web hosting, file sharing, and application access.

In contrast, routers direct data traffic between different networks and ensure that packets of data reach their intended destinations, but they do not provide data on request. Hubs operate layer 1 of the OSI model and simply transmit data received from one device to all connected devices without filtering or processing requests. Switches work at layer 2 and effectively manage traffic within a local area network by forwarding data only to the specific destination device, but they do not respond to data requests in the way that servers do. Thus, the function of a server in responding to client requests makes it the correct choice.
