How does www work

To access a web site or web page, you first open a web browser.

Enter the URL of that website/webpage in the address bar of the web browser.

A URL is a human readable form of the IP address of a web page that shows the location of that web page.

The URL is sent to the DNS (Domain Name Server) through the HTTP protocol.

DNS converts that URL into an IP address so that the system can understand it and sends it back to the browser.

From the IP address, the browser gets to know in which server that website/web page is stored.

A request is sent to that server to access that website/webpage.

When the server finds that page, it sends it to the browser as an HTML page.

Your browser renders the HTML page on your screen.
