What is a domain and is there a difference between Domain and Web Site?

Well ... how can i tell you....The Domain is only the "name" of the website... like "google.com", is a name, this name point to a server, and the server host a website.

So you have to get the name and site seperately?

yes.
you need a domain name, a website, and a web hosting server for host the website files.

Note: Hostony offer in some packages a "Free domain", the staff will tell you best.

greetings.

OK...Thank you for your help!
