what is cc

In email communication, CC stands for "carbon copy". It is a way of sending a copy of an email to someone who is not the primary recipient listed in the "To" field. The CC field is used to inform additional recipients that the email has been sent to them for their information only, indicating that no reply is required or expected. The email addresses in the CC field are visible to the main recipient, and they can decide whether to reply to the sender only or to also include the CCed addresses. The use of CC in email communication has its roots in the days when carbon paper was used to make copies of letters.
