The correct answer is: B. Video message
A paging system is a two-way radio system that uses short-range radio waves to send and receive messages. It is used to send short messages to a group of people, such as employees or students. The messages can be text, numeric, or voice messages.
Video messages cannot be sent with a paging system because they require a higher bandwidth than the system can provide. Paging systems are designed to send short, simple messages, and video messages are too large for the system to handle.
Alphanumeric messages are text messages that can include letters, numbers, and symbols. Numeric messages are messages that only contain numbers. Voice messages are messages that are recorded and played back.
Here are some additional details about each option:
- Alphanumeric messages are the most common type of message sent with a paging system. They can be used to send short messages, such as reminders or alerts.
- Numeric messages are used to send messages that only require numbers, such as PIN codes or account numbers.
- Voice messages are used to send longer messages, such as instructions or updates.
