I have a domain registered with godaddy. i want to attach it with my bolg in wrodpress or blogger. can someone tell me how to do it in details? i am new in this field so please write in details. Thanks in advance,
just edit your domain's nameservers at godaddy to point to your web host(the name servers can be obtained from your web hosting provider). add your new domain as an addon domain at your web hosting cpanel. upload your wordpress files to your host and install it.... Finished.
If you're using Wordpress.com for your blog, log into your admin panel and click "Upgrades" (last option on the sidebar). Then click the "Domains" option, enter your domain name and click "Add domain to blog". There is probably a similar process at Blogger. Of course, you still need to edit the nameservers at GoDaddy like Cupid said. Post or PM if you run into a snag. Best of luck.
This is called domain mapping. You can read about how to setup here http://support.wordpress.com/domain-mapping/
