Definition: DNS, or Domain Name System, is a collection of databases that translate hostnames to IP addresses.
DNS is often referred to as the Internet's phone book, converting easy-to-remember hostnames, like www.google.com, to IP addresses, like 74.125.224.83.
DNS servers are dedicated computers that manage the Domain Name System on the Internet
Examples:
"The Internet would be very hard to navigate it it wasn't for DNS."
