What is the primary role of a client in a client-to-server communication model?

In the client-to-server communication model, the primary role of a client is to make requests for services. Clients are typically applications or devices that initiate communication with a server to access resources, data, or functionalities offered by that server. This relationship is characterized by the client sending requests for specific operations, such as retrieving a webpage, accessing a database, or submitting a form.

The client's actions drive the interaction; it waits for a response from the server once the request has been made. This request-response model is foundational to many networked applications, where the server processes incoming requests and sends back the appropriate data or services. Understanding this role is crucial for anyone involved in IT, as it defines how applications communicate over a network and highlights the dependency of client requests on server responses.
