What is a server in terms of information systems?

A server in the context of information systems refers to a system that provides data and services to clients. This definition encapsulates the core function of a server, which is to handle requests from client devices (like computers and smartphones) and deliver the necessary information or resources. Servers can perform a variety of tasks, including hosting websites, managing emails, or holding databases, and they operate over a network to serve multiple clients simultaneously.

The concept emphasizes the role of servers in facilitating communication and resource sharing within a network. While servers can store data, they are not merely storage devices; their primary attribute is the ability to respond to client requests and provide the requested services or information in real-time. This dynamic interaction is what makes servers integral to client-server architectures in information systems.
