For example, a hard disk drive has a total storage capacity, a used storage capacity, a free storage amount, or an internal temperature. This is the request and response model of client-server networking, also known as the call and response model.Ī server will often perform numerous additional tasks as part of a single request and response, including verifying the identity of the requestor, ensuring that the client has permission to access the data or resources requested, and properly formatting or returning the required response in an expected way.Īs devices on a network operate, various settings, parameters, and states can be measured and generated at any given time. The server receives this request and responds with the appropriate information. When a client requires data or functionality from a server, it sends a request over the network. In another example, an Apache web server responds to Internet browser requests via an additional application, Apache, installed on top of an operating system. Additionally installed roles or services increase which kinds of client requests the server can respond to. This functionality can exist as part of the operating system as an installed application, role, or a combination of the two.įor example, Microsoft’s Windows Server operating system provides the functionality to listen to and respond to client requests. To function as a server, a device must be configured to listen to requests from clients on a network connection.
