ITPEC IP October 2021 Question 34

Topic: Networks

When Mr. A sent an e-mail to Mr. X, he decided to also send it to Mr. Y and Mr. Z for reference. However, Mr. A did not want Mr. X nor Mr. Y to know that it was sent to Mr. Z. In such a case, which of the following is the appropriate combination of recipients to specify?

OptionToCCBCC

Explanation

To: X, CC: Y, BCC: Z — X is the addressee, Y gets a visible copy for reference, and Z gets a hidden copy.

  • •To — the main recipient; every recipient sees the To addresses
  • •CC (carbon copy) — recipients sent the message for reference; every recipient sees the CC addresses
  • •BCC (blind carbon copy) — recipients who get the message while their addresses are removed from what the others receive

Z must receive the mail, but neither X nor Y may learn it, so Z goes only in BCC, and Y, a visible reference copy, goes in CC.

Answer (a)

Why not others:

  • •(b) — also lists Z in CC, so X and Y see Z's address
  • •(c) — puts Z in CC, where X sees it, and Y in BCC, hiding the wrong person
  • •(d) — lists Y and Z in To as well, so Z's address is shown to both X and Y

Key rule: An address in To or CC is visible to everyone who receives the mail; only BCC hides a recipient, and listing that recipient in any other field as well undoes it.
