What role does a server play in a network?

A server acts as a host computer that provides resources, services, or data to other computers on a network, commonly referred to as clients. This can include serving web pages, storing files, or managing access to applications and databases. Servers are typically characterized by their ability to handle multiple requests from clients simultaneously and respond with the requested resources.

In a web context, when a user enters a website address in their browser (the client application), a request is sent to a web server, which processes this request and delivers the appropriate web pages or data back to the client. This interaction is a fundamental aspect of how the internet operates, as servers are the backbone that enables content delivery and resource sharing across networks.

Other available options, such as a client application for web browsing, a software tool for web development, or a database management system, do not define the primary role of a server in a network. Instead, these roles focus on specific functionalities that can exist alongside or in conjunction with server infrastructure, rather than encapsulating its main purpose.
