Registering a domain name and hosting one is frequently mistaken by many people to be the same thing. These are in fact two separate services - the domain name registration is the actual name and nothing else, while the hosted domains feature reveals the amount of already registered domains you can accommodate within the same web hosting account and have website files and e-mails for them. Your sites will function in exactly the same way regardless of whether the domain addresses are registered and hosted in one place or are registered with company A and pointed to company B. Simply registering a domain name without hosting it will give you ownership, but will not enable you to have a web site if you don't host this domain name in some account so that records for it are created and it starts opening the content from that account.
