Lay out the process
- Full namewww.example.com
- wwwA common subdomain label
- example.comCan also be configured to serve a website
www comes from World Wide Web and is often used as a label in a website’s hostname.
It is a convention, not a prefix every website must use. An administrator can configure the www and non-www names to point to the same service or to different services.
