A domain is simply the web address you type into your browser. For instance you would type www.yahoo.com in your browser to go to Yahoo's web site. The most common extensions are ".com - .net - .org.", however there are many more. Today, domain names are easy and affordable to reserve. The average price for a domain is anywhere from $6 to $35.

Domain names are officially managed by the worldwide organization ICANN (The Internet Corporation for Assigned Names and Numbers). When you purchase a domain name you purchase it through a registrar that has been accredited by ICANN. Many web hosts will reserve your name for you, but the advantage to reserving your domain through a pure domain registrar is in the versatility of being able to switch hosting providers, and most likely get a better price.
