What is a benefit of using client/server network?

The answer is centralization

A client-server network is a server which acts as one powerful computer that provides information to other sub-ordinate workstations called the client. The biggest benefit of this setup is centralization or the central management of the server. Only a single server functions as a host that all clients request and use. Having a single centrally managed server is cost effective and is easily manageable. This centralized control can also be used to deploy processes, allocate user resources and delegate access permissions easily and effectively.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
