DNS
A system which maintains a relationship between Internet Protocol (IP) addresses and domain names. Computers use the DNS system to electronically transmit data with other computers through the internet. DNS is actually comprised of a set of database servers which maintain the relationship between IP addresses and domain names and facilitate the lookup between the two.
