what is work of dns..

Answer / info7shankar

1) Short for Domain Name System (or Service or Server), an
Internet service that translates domain names into IP
addresses. Because domain namesare alphabetic, they're
easier to remember. The Internet however, is really based on
IP addresses. Every time you use a domain name, therefore, a
DNS service must translate the name into the corresponding
IP address. For example, the domain name www.example.com
might translate to198.105.232.4.
The DNS system is, in fact, its own network. If one DNS
server doesn't know how to translate a particular domain
name, it asks another one, and so on, until the correct IP
address is returned.
(2) Short for digital nervous system, a term coined by Bill
Gates to describe a network of personal computers that make
it easier to obtain and understand information.

Answer / alf55

The idea of the "dns" dates back to "The NIC Name Server--A
Datagram Based Information Utility" (rfc #756) from July 1979.

Sorry, well before Bill Gates.

But the major implementation was BIND (November 1983)
(meaning is "Berkeley Internet Name Domain" written for
Unix),also be any Microsoft software was network aware.

The purpose is much like a phone book where it takes a
"name" (properly formatted) and turns it into an IP ADDRESS
(which works like a phone number to the computer). The
computer really looks more like a PBX system as the "port
number" is then route to the service being requested.
