How_Web_Server_Works

Web server is a program that uses HTTP to serve files that create web pages to users in response to their requests, which is sent by their computers HTTP connection.

Any server that delivers an XML document to another device can be a web server. A better definition might be that a web server is an Internet server that responds to HTTP requests to deliver content and services.

Let me explain you with a simple example, I can say if you are in front of your computer, browsing your web, and you get a message from a friend saying, "I had just read a great article at the following URL http://www.fastwebhost.in/blog  

So you will type that URL into your browser and press enter.

And that’s it, no matter on which web server the website is in the world, it dispalys the page on your computer screen.

Always a web server is connected to the internet. Every web server that connects to the Internet will be having an unique address which contains a series of four numbers between 0 and 255. A period (.) separates these numbers​.

Also, web server enables the hosting providers to manage multiple domains(users) on a single server.
