A web server stores and delivers the content for a website – such as text, images, video, and application data – to clients that request it. The most common type of client is a web browser program, which requests data from your website when a user clicks on a link or downloads a document on a page displayed in the browser.
A web server might also cache content to speed delivery of commonly requested content. This process is also known as web acceleration.
A web server can host a single website or multiple websites using the same software and hardware resources, which is known as virtual hosting. Web servers can also limit the speed of response to different clients so as to prevent a single client from dominating resources that are better used to satisfy requests from a large number of clients.
While web servers typically host websites that are accessible on the Internet, they can also be used to communicate between web clients and servers in local area networks such as a company’s intranet. A web server can even be embedded in a device such a digital camera so that the users can communicate with the device via any commonly available Web browser.
