A web server is a crucial component of the World Wide Web. It plays a vital role in delivering web content to users by processing their requests and sending the appropriate responses. In this article, we will delve into what a web server is and explore its different types.

What is a Web Server?
A web server can be defined as a software or hardware system that serves web pages to clients upon request. When you enter a website’s URL into your browser, it sends a request to the web server hosting that particular website. The server then processes the request and sends back the requested webpage to be displayed on your screen.
