What is a sub domain?

Most people are unaware but they already use sub domains on a daily basis. The famous "www" of the World Wide Web is the most common example of a sub domain. Sub domains can be created on a DNS server and they don't need to be registered with a domain registrar, of course, the original domain would need to be registered before a sub domain could be created. Common examples of sub domains used on the internet are http://store.apple.com and http://support.microsoft.com.
