CNAME records alias a record to an existing "A" record. The "A" record equates name to IP. CNAME will equate another name to the name you defined in the A record. This way if the IP of the A record changes you don't have to change all the alias (CNAME) records to get them to go to same IP.

Ok then, you answer a couple questions for me first:
1. What is your native language?
2. How new are you to linux
and more importantly.
3. Why do you need to know this?

I ask these questions so I can gain a bit of context and understand exactly what you're looking for...

Cname record is short for conical name record, it's a type of resource record in the DNS (domain name system) that tells you the the domain name is just another name for another conical domain name.
in short:
It's used to help run multiple services (like ftp and a webserver; that run on different ports)from a single IP address.
