In a bus network, how are signals broadcasted?

In a bus network, signals are broadcasted in both directions to the entire network. This is a fundamental characteristic of bus topologies. When a device sends a message, that signal travels across the entire bus – the common communication line – and every device connected to the bus receives the signal. Each connected device checks the address on the message to determine if the message is intended for them. If the address matches, they process the message; if not, they ignore it. This method of broadcasting enables simple and effective communication in a network, but it can also lead to data collisions if multiple devices attempt to send signals simultaneously. The design of a bus network emphasizes simplicity and cost-effectiveness while facilitating communication among multiple devices.

The other options reflect different networking topologies or methods of signal transmission that do not align with how a bus network operates.
