Domain names are much like VIN number of a vehicle, there are no two that are exactly the same.
Domain names are the identity cards of the Internet, representing the face of each website. In basic terms, a domain name is simply the name of your web site. However, behind each domain name is a process that turns a local web address into a word or phrase that anyone can use to access your site from around the world. Domain name is a phrase or even just a word that people input in their browsers to be pointed directly to a specific web site.
The first thing you should do when you are ready is to select a domain registrar and then open an account with them. Once you have registered you will need to choose your domain name and make sure it is available. The registrar will be able to provide you with your login information so that you may use their interface to edit the name servers and other domain properties.
Your name servers will dictate what web site or server your domain name represents. Your hosting account contains the names of the name servers that you need to point your domain to. Simply log into the control panel of your web hosting account, and you can find your name server information, or just call your hosting company and ask them for it.
A name server is a web server assigned with the sole task of sending and receiving request pertaining to domain names and IP addresses. The job of the domain name server is to take a number like an IP address and turn it into a readable term that can be typed into a browser’s address bar, or vice versa.
Computers read Internet addresses much differently than humans. All computer language is in numbers and not letters. Therefore, in order for information to be transmitted from the nameserver to a user’s computer, the DNS has to transmit information pertaining to the address and meaning of the domain name. The domain name system is a basically the largest database in the world, receiving more requests than any other database.
