What describes a client-server model?

The client-server model is fundamentally a design framework for networking in which multiple clients are able to request and receive services from a centralized server. This model enhances efficiency and organization within network communications. In this structure, the server acts as a powerful centralized system that manages resources, processes data, and provides various services to the connected clients, which are typically less powerful devices that rely on the server for functionalities.

This model is widely used in various applications, such as web services and database management systems, where clients send requests to the server and the server processes these requests to deliver the required information or service. The ability for multiple clients to simultaneously connect to a single server maximizes resource utilization and streamlines communication across the network.

In contrast, the other options do not accurately capture the essence of the client-server model. For example, a system where all devices operate independently represents a decentralized approach rather than the hierarchical and centralized nature of a client-server model. Peer-to-peer communication, which allows devices to connect directly with one another without a central server, also deviates from the client-server structure. Similarly, a setup where each client has its own server suggests a dispersed system that contrasts with the consolidation of resources typical of a client-server environment.
