What are the difference between CCand BCC?

Answer 1

CC is short for carbon copy. People whose addresses go in the cc field of an e-mail are people who get a copy of the e-mail even though it is not addressed to them. For example, if you are sending an e-mail on someone else's behalf, the person for whom you are sending the e-mail gets a copy.

BCC is short for blind carbon copy. The usage is the same as for cc, but the names and addresses in the bcc field are hidden from everyone receiving the e-mail.

Before personal computers were available, if you were sending a message in writing and you wanted it to look professional, you used a typewriter. If you wanted to have an extra copy of the letter you were typing, you would put two sheets of paper into the typewriter with a sheet of carbon paper in between. As you typed, ink from the carbon paper would make a copy of your text on the second page, which was called a carbon copy.
