DNS acts like a virtual phone operator for the internet and local networks. When any end user typed in ww.anyName.com or \\YourServerName both of these requests hit up a DNS server to ask it a simple question.

Where is this website or computer located. The DNS server returns a IP address (just like a physical street address) and then your browser can find it.

This the simple way DNS works..

DNS also serves as the "phone book" for the Internet by translating human-readable computer hostnames,into the so called IP address that networking equipment needs for delivering information.and Like this way message transfers.

I will explain with the daily example like the telephone system, every telephone no has the unique number in the same way, any computer attached to the Internet has a unique number, that is its IP address. Also like the telephone system there is a directory inquiries service to help you find those numbers, and in the internet world it is referred to as the DNS.

Likewise, if you know a server's host name you can give that name to a DNS server and it will give you the IP address of that server.
