Which of the following is NOT an example of electronic communication?

• A. Noticeboard
• B. Email
• C. Intranet
• D. PA system

Answer: (A)

The key idea is telling apart methods that use electronic systems to send messages from those that don’t. Electronic communication relies on devices or networks to transmit information. A noticeboard is a physical board where messages are posted for people to read in person; there’s no electronic transmission involved, so it isn’t electronic communication. The other options all rely on electronic means: email uses computers and networks to send messages; intranet is a private digital network for sharing information; a PA system uses microphones, amplifiers, and speakers to convey messages electronically. So the noticeboard is the example that isn’t electronic communication.
