What is a Web Server?

A web server is both software and hardware that processes requests via the HTTP or HTTPS network protocols, which are used to deliver web content. When a user agent, such as a web browser or web crawler, requests a web page or resource using HTTP, the web server responds with the content or an error message. Additionally, a web server can accept and store resources from the user agent if configured to do so.

The hardware for running a web server varies based on the volume of requests it needs to handle. It can range from embedded systems, like a router’s small web server for configuration, to high-speed computers in large data centers handling millions of requests for high-traffic websites.

Web servers are necessary for delivering content over the internet, similar to how multimedia servers handle large volumes of media content. If you’re interested in setting up a multimedia server, you can explore detailed steps and considerations in this guide on building a multimedia server in 2024.
