Two station A and B are connected via a point to point Link.A sends a freame to B using Go back-n protocolwith window size 7 and sequence number is of 3 bit.A sends frame one by one but B's ack for frame 3 is not reached ... ACK4,but frame 5 is lost and not received by B..so now what will be the buffer frame of current window of A?
