Which kind of distribution sends audio from one source to all devices?

The correct response focuses on the concept of broadcast distribution in networking and how it functions in the context of audio transmission. Broadcast distribution sends audio signals from a single source to all devices on a network segment without any specific targeting. This means that every device connected to the network receives the same audio stream simultaneously, making it efficient for scenarios where the same content is needed by all devices, such as public address systems or simultaneous audio feeds in an event.

In a broadcast scenario, the system does not have to manage individual connections to each device, which simplifies the distribution process. This is particularly useful in environments where the number of recipients is large, allowing for easy scalability and deployment of audio over a network.

In contrast, unicast refers to a one-to-one communication model, where audio is sent from one source to a specific single device, requiring individual streams for each device. Multicast allows for one-to-many communication, but it targets a specific group of devices rather than broadcasting to all. Anycast sends data to the nearest device in a group of potential receivers, which is different from broadcasting to all devices. Understanding these distinctions clarifies why broadcast is the most suitable choice for sending audio from one source to all devices in a network.
