What is the Client/Server model used for?

The Client/Server model is fundamental to understanding how network communications operate. It describes a system where multiple clients (users or devices) request services or resources from a centralized server. This model enables efficient distribution and management of tasks, as clients can send requests for data or services, and the server processes those requests and returns the needed information.

This architecture is widely used in networking because it helps organize interactions between devices that request services and the servers that provide them, illustrating the flow of information and the dependencies between users and resources. For example, when you access a website, your browser acts as the client, sending a request to the web server, which then processes the request and sends back the appropriate webpages or data.

In contrast, the other options each describe different concepts or functions that do not encapsulate the primary purpose of the Client/Server model. Monitoring user activity, personal computer management, and internet security protocols do not focus on the specific interactions and roles defined by the Client/Server framework in networking.
