Domain Names

Domain names are a special name that you can apply to your website. Once you apply it to your website, users can reach your website by typing this domain name into the browser's address bar. Examples of domain names are quackit.com, great-workout.com and google.com. You can reach the "great workout" website by typing its domain name (great-workout.com) into the address bar.

Most websites have a www subdomain applied to their domain name so that you can reach the website by typing "www" followed by the domain name (eg, www.great-workout.com). This is done on the DNS server after you've registered the domain name, and has nothing to do with the domain name itself (i.e. you can add www to any domain name). You can also add other subdomains as you wish.

Furthermore, you can reach any page on a website by typing the domain name followed by the path to the page. For example, www.great-workout.com/nutrition/index.cfm

Only one person/company can own a domain name at any time. Therefore, if you want mycompany.com but someone else has it, you will need to either find another name, or make them an offer to buy it. You could also wait for it to expire and hope they don't re-register it, but you could be waiting a long time.
