Propagation delay is defined as what?

The Time It Takes For A Signal To Travel From One End To The Other The Time It Takes For A Signal To Travel From The Source To The Destination In A Path The Time For A Signal To Degrade The Time It Takes For A Packet To Reach Its Destination

Correct Answer:

The Time It Takes For A Signal To Travel From The Source To The Destination In A Path

Explanation:

Propagation delay is the time it takes for a signal to propagate from the source to the destination along the transmission path. It depends on the length of the path and the medium’s propagation speed (velocity factor); in copper, signals move at a significant fraction of the speed of light, so the delay grows with length. This delay is strictly the travel time through the cable and does not include processing, queuing, or other network delays, nor the signal’s degradation.
