In the term of networking the Domain Name System (DNS) is a most common word. it is like a phonebook of the Internet. The Peoples can access information online through domain names, like mindstick.com or espn.com. The web browsers are interact via Internet Protocol (IP) addresses. Into the Domain Name System (DNS) translates domain names to IP addresses so browsers can load Internet resources.

Internet world in its early days was very small, that was easier for humans to correspond specific IP addresses with specific computers, but that didn’t last for long as more devices and people joined the growing network. That is still possible to type a specific IP address into a browser to reach a website, but then, as now, people wanted an address made up of easy-to-remember words, of the sort that we would recognize as a domain name (like networkworld.com) today. Around 1970 and 1980, those names and addresses were assigned by one person — Elizabeth Feinler at Stanford – who maintained a master list of every Internet-connected computer in a text file called HOSTS.TXT.
