We pick g.root-servers.net, one of the 13 root servers (1), and ask it about www.chetanasforum.com and learn that com is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that chetanasforum.com is delegated to two name servers, including ns2.chetanasjava.com (3), so we ask that one where we see a CNAME from www.chetanasforum.com to chetanasforum.com, so we have to start all over again. We already know that ns2.chetanasjava.com is authoritative for chetanasforum.com (4) and ask it about chetanasforum.com and get the following answer:
