What is DNS?

Domain Name System or DNS is a system which translates the website domain name to their unique IP addresses. Each Website, Computer System, Tablet or Mobile has  a unique IP Address which identifies that website or system distinctively over internet. As the IP addresses are hard to remember for a human, the websites are given a domain name. The same domain which we use to access through  our browser. As we request any website or webpage from our browser the DNS comes into play. The DNS checks IP for the requested domain in root servers and translates the domain into respective IP address, which in turn use to get an response for the user.
