Hosts A and B are communicating over a TCP connection. Host A sent $126$ bytes of data, and Host B did not send any data. Host A uses port $302,$ and host B uses port $80.$ Up to now, all data sent by each side have been received, acknowledged, and consumed by the respective applications. The client and the server each have a RcvBuffer of $2048$ bytes, and neither side$$s application reads any of the bytes received during the TCP activities indicated below. Suppose Host A then sends two data segments to Host B back$-$to$-$back. The first and second segments contain $80$ and $40$ bytes of data, respectively. Host B sends an acknowledgment whenever it receives a segment from Host A$.$
