Question: True or false problems (If false, explain why). (a) Suppose Host A sends one segment with sequence number 38 and 4 bytes of data over

True or false problems (If false, explain why).

(a) Suppose Host A sends one segment with sequence number 38 and 4 bytes of data over a TCP connection to Host B. In this same segment the acknowledgment number must be 42.

(b) Consider congestion control in TCP. When the timer expires at the sender, the value of ssthresh is set to one half of its previous value.

(c) In the slow start stage of TCP, the congestion window size doubles for each RTT. Equivalently, the sender doubles its cwnd whenever it receivers a new ACK.
