Domain names [yourname.com]are actaully easy-to-remember shortcuts to a static numeric IP address. As you type "www.yourname.com”, your browser resolves to the associated numeric IP address. DNS, the Domain Name System, is what connects the human-preferred domain names with the computer-preferred IP addresses.

As user types, www.some-name.com, the browser tries to resolve the domain name in local DNS and then routed through ISP to the Global DNS servers and finally reached to the server and web server will recieve the request and delivers the files as requested in the domain name.
