Which of the following describes a device that requests services from a server?

A device that requests services from a server is referred to as a client. In a client-server architecture, the client is the entity that initiates communication with the server to access resources or services. This interaction typically involves sending requests for data, processing, or other types of services that the server provides.

In contrast, a database serves as a storage system for data and is usually managed by a server; it does not actively request services. A kernel is a fundamental part of the operating system that manages system resources and facilitates communication between hardware and software; it is not involved in client-server interactions in the same way. An application may act in the role of a client by making requests to a server, but not all applications inherently operate as clients. Therefore, the most accurate term that encapsulates the role of requesting services from a server is the client.
