Domain name extensions
There are many domain name extensions, global ones like .com, .net, .org, .info and .biz;; AU domains such as .com.au and national domains for all nations on the planet, .fr, .de, .jp, .it, etc. There are some national domains that have taken on a global significance, for instance the national domain of Tuvalu in the South Pacific, .tv, is used globally by multimedia and television companies. The .ws domain of Western Samoa is used globally as an acronym of "website".
When you register a domain name you have control of it but you cannot yet make use of it. To create a web site or use it for email you need web hosting.
