TLD : Top Level Domain. Examples are .com , .net , .org , .info , .gov
ccTLD : Country-Code Top Level Domain. Examples include .co.in , .co.uk , .gd , .tv
This has nothing to do with the "site" where you registered your domain.
A .com will be called a TLD no matter where it's registered (godaddy, namecheap, DRN [ddboard], etc.)
Hope this helped.
