What is the role of a Server?

The role of a server is best described as the central computer that all clients connect to on a network. Servers are designed to provide resources, data, services, or programs to other computers, known as clients, over a network. In the context of web development, a server hosts websites and serves web pages to users' devices (clients) when requested.

This central role is vital for network operations because it streamlines the communication process between different devices, ensuring that clients can access the files and services they need efficiently. For example, when a user types a URL into a web browser, the browser sends a request to the server, which then processes that request and sends back the appropriate content, such as a webpage.

Other options describe functions that are not the primary role of a server. While servers do provide web content to clients, they don’t necessarily display websites directly on devices; this is the role of a browser. Furthermore, they do not manage internet service providers or enhance browser functionality, which are distinct functions pertaining to different aspects of internet and software operation.
