Sub-domain Name

A domain name that is part of a larger domain. If you’ve ever seen a web address that doesn’t start with the letters “www” then you’ve encountered a sub-domain.

Sub-domains are like secondary sites within the larger domain. If you think of the larger domain as a file cabinet, the sub domain would be the folders. Some examples of sub-domains are “news.google.com” or “mail.yahoo.com.”
