carbon copy (CC)
Carbon Copy(CC) is an entry on the distribution list of electronic messages:"Copy to". The carbon copy is used to inform other people besides the actual recipient of the e-mail.
The main recipient of the mail can see from the address field whether a copy has gone from the e-mail client and to whom. Likewise, the recipients of the copy can see who the main recipient is and who received the copy. The situation is different with Blind Carbon Copy( BCC), where the recipients cannot tell who has received a hidden copy.
The term Carbon Copy means carbon paper copy and comes from the classic office technology when letters written on a typewriter were duplicated by depositing carbon paper. At that time, one also spoke of carbon copies.
