A CNAME (Canonical name) record, is basically an alias or nickname for another domain. It is often used instead of an A record to point different hostnames to the same location. The difference between the record types is that an A record always points to an IP address, while a CNAME always points to another name.
A CNAME is often used to point a subdomain on your domain to an external service, like for example Office 365 or Blogger.
