Initially the Internet was built on the notion that any computer on a global network can be identified by its numeric Internet Protocol (IP) address. But since people, are the primary users of the Internet, a more people-friendly naming system called the Domain Name System (DNS) was invented This System translates a domain name such as 1stDomain.net into Internet Protocol (IP) numbers to find the correct web site - in this case the site for 1stDomain.net. The data is then made available to all computers and users on the Internet.
