ADVANTAGES OF A DOMAIN NAME

Having your own domain name gives you control of your own email and your presence on the web. A domain provides a permanent address that is easy to remember and doesn't change with physical relocations and job changes. It is like your real estate in the Internet world.

You can use the address to develop your online property called WEBSITES. Your email is delivered to the inbox of that location, i.e.,address of the domain.
Besides, you get to own the domain name for a particular period of time(minimum being 1 year) at a minimal cost just that anybody can afford.
Moreover, domain names are transferable.
They can be sold at any given point of time.
They can be parked and you can generate money doing nothing, absolutely nothing.

Having numerous advantages, there is no reason for you not to have a domain name.
Either you profit from it or at the most, you BREAK EVEN. There would be NO LOSS in registering a domain be it the minimal registration fee.
Registering a domain name is done through a REGISTRAR who manages the domain for you in a master registry and handles a billing.
One of the biggest registrar companies in this market is GoDaddy.com
It is the biggest service provider and has excellent support system.
