50. What is a Domain Name Server?
Domain Name server also known as name server is like a storage space, a huge database which maps the domain names to IP addresses.
Each domain name which has a website has to be connected to a name server, also known as DNS server for the computer to figure out which IP address is to be used for a particular domain name so the correct web pages can be shown.
Once a domain name is purchased it is important to point the domain to hosting name servers so that the website will show for that domain name. This is done by adding name server data to the domain names information panel. Once done the domain will point to the name servers and thus your website will show for that domain name.
