Which of the following terms describes a computer's role when connected to a network?

A computer's role when connected to a network can be described as a client if it is designed to access services or resources provided by another computer (the server) over the network. In a client-server architecture, the client is typically the device that requests information or services, operates applications, and displays results to the user.

This relationship is fundamental to how many applications and services function in a networked environment. For example, when a user accesses a website, their browser acts as a client that requests information from a web server, which then delivers the requested data back to the client for display.

The other options reflect different roles: a host is a more general term that refers to any device connected to a network, a server is a computer that provides resources or services to clients, and a database is a structured set of data held in a computer, not a role in a network connection. Understanding these distinctions clarifies why describing a computer as a client accurately captures its function in the context of a network.
