Explanation:
Detailed explanation-1: -The receiver accepts packets only in sequence; it does not buffer packets received out of order. Consequently, if the transmitter sends N packets and if the first is lost, then it must resend all the N packets starting from the first one. Hence the name Go-Back-N.
Detailed explanation-2: -If acknowledgment for a frame is not received, the whole window of frames is retransmitted instead of just the corrupted frame. Retransmission of all the frames on detecting a corrupted frame increases channel congestion and also increases the bandwidth requirement. More items •12-Jul-2022
