A domain name is an identification string that defines a realm of administrative autonomy, authority, or control in the Internet. Domain names are formed by the rules and procedures of the Domain Name System (DNS).
Domain names are used in various networking contexts and application-specific naming and addressing purposes. In general, a domain name represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet.

Tips for Choosing the Right Domain Name
Brainstorm 5 Top Keywords;
When you first begin your domain name search, it helps to have 5 terms or phrases in mind that best describe the domain you're seeking. Once you have this list, you can start to pair them or add prefixes & suffixes to create good domain ideas. For example, if you're launching a mortgage related domain, you might start with words like "mortage, finance, home equity, interest rate, house payment" then play around until you can find a good match.
Make the Domain Unique;
Having your website confused with a popular site already owned by someone else is a recipe for disaster.
Only Choose Dot-Com Available Domains;
If you're not concerned with type-in traffic, branding or name recognition, you don't need to worry about this one. However, if you're at all serious about building a successful website over the long-term, you should be worried about all of these elements, and while directing traffic to a .net or .org (as SEOmoz does) is fine, owning and 301'ing the .com is critical. With the exception of the very tech-savvy, most people who use the web still make the automatic assumption that .com is all that's out there - don't make the mistake of locking out or losing traffic to these folks.
Make it Easy to Type;
If a domain name requires considerable attention to type correctly, due to spelling, length or the use of un-memorable words or sounds, you've lost a good portion of your branding and marketing value. I've even heard usability folks toute the value of having the letters include easy-to-type letters (which I interpret as avoiding "q," "z," "x," "c," and "p").
Keep the Name as Short as Possible;
Short names are easy to type and easy to remember (the previous two rules). They also allow for more characters in the URL in the SERPs and a better fit on business cards and other offline media.
Create and Fulfill Expectations;
When someone hears about your domain name for the first time, they should be able to instantly and accurately guess at the type of content that might be found there. That's why I love domain names like Hotmail.com, CareerBuilder.com, AutoTrader.com and WebMD.com. Domains like Monster.com, Amazon.com and Zillow.com (whom I usually praise) required far more branding because of their un-intuitive names.
Reject Hyphens and Numbers;
Both hyphens and numbers make it hard to give your domain name verbally and falls down on being easy to remember or type. I'd suggest not using spelled-out or roman numerals in domains, as both can be confusing and mistaken for the other.
