DNS

Full Title or Meme

Domain Name System DNS is the term for a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates more readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols. By providing a worldwide, distributed directory service, the Domain Name System has been an essential component of the functionality of the Internet since 1985.

Context

In order to ensure the global uniqueness of a domain (host) name there is only a single root where all top-level domain (TLD) names are registered. Every country gets there own TLD, for example US or EU. Other TLDs are assigned by the IANA.
