What is the nature of broadcast transmission?

1. One-to-one communication

2. One-to-many communication

3. Two-way communication

4. One-to-few communication

The correct answer is: One-to-many communication

Broadcast transmission is characterized by one-to-many communication. This means that a single source sends data to multiple recipients simultaneously. In scenarios like television or radio broadcasting, the signal is transmitted over a wide area and can be received by any device that is tuned to the appropriate frequency or channel. This method is efficient for disseminating information to a large audience without requiring a direct connection to each individual receiver. In contrast, one-to-one communication involves direct interaction between a single sender and a single receiver, which does not capture the essence of broadcasting where the message is intended for a broader audience. Two-way communication implies an exchange of information where responses are expected from both parties, distinguishing it from the typically unidirectional nature of broadcast transmission. One-to-few communication implies a limited audience, which again does not align with the fundamental purpose of broadcasting to reach as many receivers as possible.
