In networking, what does a server do?

A server is fundamentally a device that provides data, services, or resources to other devices on a network, which are known as clients. This can include web hosting, file storage, email services, and more. When a client requests information or a service, the server processes that request and responds accordingly, enabling the client to access resources efficiently.

The nature of servers is to manage and serve multiple clients simultaneously, unlike other devices that may have more specialized or limited functions. For instance, while data storage devices hold data, they do not provide services beyond storing and retrieving that data. In contrast, servers are integral in facilitating communication and resource sharing within a network, acting as centralized points for service management.
