Registering a domain and hosting one is sometimes mistaken by a lot of people to be one and the same thing. They are actually two different services - the domain registration is the actual name and nothing more, while the hosted domains feature reveals the number of already registered domains you can accommodate in the same website hosting account and have website data and e-mails for them. Your websites will function in precisely the same way regardless of whether the domain names 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 until you host this domain name in some account so that records for it are set up and it starts opening the data from that account.
