How web servers work?
A Web server uses traditional client-server model. Here, the server is a web server and client is web browser. The user sends a request via a web browser to the server to call a webpage. The request sent by the web browser is taken by the web server and it processes the request and sends the webpage to the browser.

Now the web browser displays the webpage to the user. This whole process happens within a just few seconds. Here, web browser and the web server are communicating and this communication is done using Hyper Text Transfer Protocol (HTTP).

For clarity, we take an example, the user type a URL “apple.com/itunes” to visit itunes page in apple website in web browser. The Web browser then converts the request of the user to machine understandable language, and sends it to Web server. The Web server then checks for domain name “apple” and then for “itunes” and send it to web browser. The Web browser receives the itunes page in machine language, converts it to user understandable language, and displays the website to the user. In this client and server communication process, they use HTTP as the language of communication.

Web server software program can be written in different computer languages like Java, C++, etc. There are many webserver software available these days.
