Each domain name ends with a period and then two or three letters. These are called top levels and each country has its top level as ex Norway: www.annec. en,
sweden: www.annec. see, etc.
In order to create a domain name in Norway (.no) one must have an organization number or be a Norwegian citizen. You can read more about the domains around .no domains at Norid.
There are also top levels that are not associated with a country, but to a function and these are called generic top-level domains and have endings like www.annec. com, www.annec. org, etc.
