What is CC, BCC   In the email 
   To compose a mail and send it when we often have friends on the Field will give the Mail IDs. But it is not the only way in and there are two ways to Send. Those Cc, Bcc.
How exactly do I use them? 

Cc: Carbon Copy
   When do we want to send a mail to two other people, then it can only work. The first person to ID the To field, Cc mail ID and the type of the others have done.
Cc have to do is type up a mail ID to put a comma between each.
Mail reader of the To, Cc, in both Field ID in the mail pals can view.
   It can be used in any place, if you want to send a mail to your boss if you want to send the same thing to someone else in the superior ID To, Cc and id's.
There is no big difference between this and the To field. 

Bcc: Blind Carbon Copy
   Bcc when sending e-mail to send you the ID and name of the person giving it, if only he knew who reads. Unnecessary and ID do not know them.
It is even safe. This Newsletter, and not many people use when sending.
Bcc have to do is type up a mail ID to put a comma between each.
To be forced to use Bcc when you do not have to give anything.
