Which Channel Is Better For Stop And Wait Protocol? Ans: In case of Stop-and-Wait protocol, the transmitter after sending a frame waits for the acknowledgement from the receiver before sending the next frame. This protocol works efficiently for long frames, where propagation time is small compared to the transmission time of the frame. In which
