A web server is a software program that listens for requests from the internet or a local network, and returns web pages in response to those requests. It serves as the intermediary between a client (typically a web browser) and the web application that runs on the server, providing dynamic content and data storage. Examples of popular web servers include Apache, Nginx, and Microsoft IIS.
