A domain name is the 'address' of a web site and each one is unique. The domain names always have 2 or more parts, dot  separated, e.g. yourname.com. When the name is in use it does not have to be prefixed with 'www' although most are configured in this way.

The first part of the name is chosen by the registrant of the name, the last part refers to the domain "leve".

The common 'Top Level Domains' (TLD's)  are .com, .org and .net. 

Second level domains contain a two-letter code specific to a particular country e.g. .uk. Each country may  provide a particular type of organisation e.g. .co.uk, .gov.uk".

The domain name in its simplest form is just an Internet Website address. Just as your house or apartment has its own unique identifying address for the post office, so does every website.

In the business world, domain names are becoming as common as telephone and fax numbers. If your advertisements and business cards don't display a domain name, you run the risk of being completely passed over by customers that prefer to browse merchandise and services online.

The good domain name is vital for a business. If the name does not match your business name or slogan then it must be closely related to one or both. Your domain name must also be easy to remember so that customers do not have difficulties to find your site online. Having a registered  domain name with a live website is sometimes the first priority for a business, because it is a very inexpensive way to get your business name and information in front of the public.
