解説
問 75
Incorrectア
The direction of notification is reversed. What is hidden is the Bcc address; the addresses in the To field or Cc field are not hidden. The recipients in the Bcc field see the addresses entered in the To field and Cc field as usual, so it is not the case that they are not notified of them.
Incorrectイ
Bcc is only a field for hiding a recipient from the other recipients, and it has nothing to do with any encryption function. Entering an address in Bcc does not cause the email to be automatically encrypted.
Incorrectウ
Bcc is a field for hiding recipients and does not affect whether attachments are present. The recipients in the Bcc field, just like those in the To field and Cc field, receive the email with its attachments intact.
- エ
正解 Bcc is short for Blind Carbon Copy. The email addresses entered in this field are hidden from the other recipients while the message is sent to everyone. Therefore the recipients in the To field and Cc field are never notified of the addresses entered in the Bcc field, and they cannot find out to whom the message was sent by Bcc. This is the original role of Bcc, so the statement in option エ (the addresses entered in the To field or Cc field are not notified of the addresses entered in the Bcc field) is appropriate.
ここがポイント
- Addresses entered in Bcc (blind carbon copy) are hidden from all other recipients, including those in the To and Cc fields, when the message is delivered to everyone.
- The key point is to correctly understand the direction of hiding: the addresses in the To and Cc fields are shown to all recipients, but only the addresses in the Bcc field are not disclosed to the other recipients.
