What computing model involves clients requesting services from servers?

The client-server computing model is characterized by a clear distinction between clients and servers, where clients are devices or applications that request resources or services, and servers are those providing those resources or services. In this model, the client initiates requests to the server, which processes these requests and returns the appropriate responses or data. This relationship allows for the centralized management of resources, scalability, and the potential for complex interactions while maintaining a clear separation of functions between the server and client. By design, this model supports various applications, from web browsing to database queries, ensuring that clients can access the required services efficiently through the server infrastructure.

The other options, such as peer-to-peer, multicast, and broadcast, describe different networking paradigms that do not fit the typical client-server interaction structure, where clients seek services from centralized servers. In peer-to-peer, all participants can act as both clients and servers, sharing resources amongst themselves rather than relying on a central server. Multicast and broadcast pertain to methods of data transmission across networks, distributing information to multiple recipients simultaneously rather than focusing on client-server specific interactions.
