Domains are a unique way to identify yourself on the Internet. There are two parts to a domain: the name and the extension. The name is the description of yourself or your site (for example, the name “dogfood” in dogfood.com). The extension represents the domain category. For example, the .com extension means “commercial,” .net means “network”, and so on. There are many extensions available: .biz (business), .info (medium sites), .us (US sites), .ca (Canadian sites), to name a few. “www” is automatically entered by the web server that hosts your site but is not part of the domain name.
You cannot use the domain name until you register it. You cannot register a domain name if it has already been registered by someone else. The registration process is quite simple:
1. Come up with a domain name and extension.
2. Select a registrar and register your domain name.
3. Find a web hosting company to host your domain name, such as servermeister.com
