What is the DNS and how it works?

When we input the domain, how can we receive the web page? Let’s study about DNS.

Basically, all computers identify each other by the number and using that number they can communicate. We called this identity number as IP Address.

But let’s think one more time. When you use the web service, you haven’t input any number, right? I convince you input the name of the web site such as www.google.com. We said this as Domain Name.
