What does 'Bcc' stand for in email terminology?

The term 'Bcc' stands for "Blind Carbon Copy." This feature is used in email communication to send an email to multiple recipients without revealing their addresses to one another. When recipients are added in the Bcc field, they can receive the email but do not see the other Bcc addresses, leading to a level of privacy that is especially useful in mass mailing situations or when discretion is needed.

In contrast, options like "Basic Carbon Copy," "Buffered Carbon Copy," and "Binary Carbon Copy" do not correspond to any established email terminology and do not accurately describe the functionality of the Bcc feature. Thus, the correct understanding of "Bcc" emphasizes both its privacy aspect and its role in email communication.
