If the ends of a bus topology network are not terminated then you will get 'signal bounce'. This will cause all packets to collide with each other, and the net effect is that the network is unusable.
Any connection failure in a bus topology will result in the network becoming unusable due to signal bounce in the affected cable.
bus
Any technology with the possible exception to token ring may be susceptible to signal bounce when one of the cable segment is disconnected or there is a short in the wire segment. An unterminated end of a wire segment will cause signal bounce because there is no termination at one of the ends to absorb the signal, preventing it from bouncing back into the cable.
Firstly,bus has no safety at all. And often had an accident. This risk can cause by driver or the circumstances at the road. The main risk is that there will be a break in the cable connections somewhere, which causes the entire network to go down due to signal bounce.

Generally it would be N - 1, assuming that the ends of the segment were terminated by a terminator to prevent signal bounce.
Echo-back interferes with the original signal
To prevent signals from being echoed back through the network
No but if the fly is hanging on to the bus then yes.
In a bus topology, the purpose of a terminator is to absorb signals at both ends of the bus cable, preventing them from bouncing back and causing network interference. Without terminators, signals could reflect back along the bus, leading to data collisions and communication errors. By ensuring proper signal termination, terminators help maintain the integrity of data transmission across the network.
