Domain name

A domain name is a name of a computer on the Internet that distinguishes it from the other systems on the network. They are sometimes colloquially (and incorrectly) referred to by marketers as "web addresses".

Top-level domains

Every domain name ends in a top-level domain (TLD) name, which is always either one of a small list of generic names (three or more characters), or a two characters territory code based on ISO-3166 (there are few exceptions and new codes are integrated case by case).
