Simply open your web browser, and type any website address in it. The browser will take you to the exact page or information that you are looking for. But, how does this happen? How could be browser so sure that the information on this server is what is needed by the user? The browser knows it because of the DNS – Domain Name System.
The fact is, when you enter your domain name in the browser, it sends a request to the DNS server which holds the lists of “domain-ip-addresses”. By searching the IP address of that particular domain, it forwards the request to the specific web server where the website data is stored and once it is found, it is resent to the browser, resulting the expected page or information the user is seeking for.
