A subdomain is a "domain within a domain", it is essentially a subdivision of a larger domain.

Subdomains are individual web addresses built upon a pre-existing domain name, for example, forums.yourdomain.com.

By convention, a subdomain should not have the prefix of "www". (This is because "www" is, itself, a subdomain).

You will see many subdomains in action on the Internet. One example is, "mail.yahoo.com" a subdomain of "yahoo.com."
