What is loop back effect in bus topology?

The loopback effect in a bus topology refers to a situation where a signal transmitted along the bus returns to the originating device rather than reaching its intended destination. This occurs when the bus is not properly terminated, causing reflections of the signal that can interfere with communication. Such reflections can lead to data collisions and network inefficiencies, ultimately disrupting overall network performance. Proper termination of the bus is essential to mitigate the loopback effect and ensure reliable data transmission.
