I have a toruble to understand the purpose of DNS server?
Thanks

DNS servers translate domain names into IP addresses.

Without a DNS server, you would have to access WebHostingTalk.com by using http://209.249.55.203

Server as I understand is a regular computer(of course with high processor). Therefore, as I understand on the DNS server in order to do that job, has to have some program for the translation from name to IP.. Am I right?

Thanks

The term server can be used to refer to both the physical machine and software running on the machine. For example, Apache is web server software, and the computer that you install it on is generally called a web server.

So, DNS = Domain Name System, the most common software used to handle DNS queries is BIND (http://www.isc.org/bind). BIND is a DNS server, also called a daemon, and the machine you install BIND on is also called a DNS server.

Of course if you were in a restaurant installing BIND on a computer, while placing your order, and getting a court summons, then you would be giving orders to a server, while receiving order from a server, and installing a server on a server all at the same time. But that's just silly :D.

Forget what everyone else said.

Start here.
