What is DNS?

DNS: 

DNS stands for Domain Name System or Service or Server.Domain Name System is an internet service that translates the domain name into internet protocols (IP) addresses.
The internet is really based on IPs, but domain name are easier to remember because they are alphabetic. Same as your mobile phone book you are unable to 
remember all the contacts and you save them with a particular name
When we use domain name, the domain name system must translate it into corresponding IP addresses.For example the domain name www.facebook.com might translate into 69.171.224.11If one DNS doesn't know how to translate a particular domain name it asks another one, until the correct IP is returned.
Here is the working of DNS,

  1. DNS means Domain Name System which helps to transfer ip address to domain name and domain name to ip addresses.It plays vital role in internet technology.For example,if you provide domain name like Google.com it convert the domain name into particular ip address.If you provide the ip address like 74.125.239.9 the
    domain name server will search for the particular website and display on your browser.DNS consist of many resource records.Some of them are A record,CNAME
    record,DNAME record etc., You can check domain to ip ,Ip to domain and DNS query using the site www.whoisxy.com
