How a web page or a website is displayed to a user in internet?

When a user enters the URL of a web page, the website is loaded. If you wish to know what happens behind the scenes, then here are the steps:

Step-1: User enters URL (Uniform Resource Locator)  in a web browser.

Step-2: Web browser creates a HTTP (Hypertext Transfer Protocol) request for the appropriate Web server.

Step-3: Web server maps this request to a particular file.

Step-4: This file is returned as a HTTP response to the web browser. HTTP header in the response shows type of content to be displayed. For this task, MIME (Multipurpose Internet Mail Extensions) is used.

Step-5: User views the webpage.
