DNS / Domain Name System (Service)
An Internet service (naming system) that translates domain names into numerical IP addresses needed for locating and identifying computer services and devices (anything connected to the Internet) with the underlying network protocols.
The Internet uses two principal namespaces -- the domain name hierarchy and the IP address spaces. The DNS maintains the domain name hierarchy and provides translation services between it and the address spaces. Internet name servers and a communication protocol implement the Domain Name System.
In other words DNS turns domains name into IP addresses that computers use to identify each other on the network. For example DNS turns "websitepulse.com" into 22.214.171.124.
