DNS is short for domain name server
What happens is a computer doesnt understand words, only binary language so it takes the name ie: www.aaa.ccc.com and reverts it to a ip address ie 192.168.5.5. and then connects to that ip address.

well each internet enabled computer has an ip ,in order to reach that computer you would need to type in it's ip , like 213.157.178.75 .this is very hard to remember as you can see, so in order to simplify things , dns was created , what it does it's to give a name to that ip, one that resembles human language.this way the user types in a website address, not an ip , then the name is sent to a dns server which tries to translate the address into an ip, if it succeds it replies to the asking computer, if not it forwards it to another dns server which might now the answer.in order to simplify things there has been employed a tree like structure , so depending on the domai ,let's say joe.server.uk the search is easier.we supose our dns doesn't know this address , it will connect to a main server and ask for the dns server that handles .uk domains , then it will connect to that server and ask for server's ip and then conect to that ip and make a final inquiry about joe.hope this helps

Every device or computer in network has a unique no. which is called IP address. It's difficult to remember this number. So there is a system called URL which gives us the facility to remember names like "www.yahoo.com" instead of remembering IP like "203.243.19.63". DNS or Domain Name System is the server which can find out the IP address behind the URL. So, when we give command to go any website, our PC first contact with DNS server to find out the IP address of that website. Then it contact that IP address directly.

Stands for Domain Name Service. It attaches a web address to an IP address.
Example:
Web address: www.teachmedns.com
IP address: 12.34.56.78
Without DNS, you wouldn't be able to go to Yahoo's website by typing in 'www.yahoo.com'. You would have to use the IP address, like the one above in the example.
DNS basically makes it easier for all of us to surf the web, instead of having to remember the actual IP address for every website.
