Explanation:
A: Bluejacking occurs when someone sends an unsolicited message to a device that is Bluetooth-enabled. Bluejackers look for a receiving device (phone, PDA, laptop) and then send a message to it. Often, the Bluejacker is trying to send someone else their business card, which will be added to the victims contact list in their address book.
