Question 1 Explanation:
S1:
TCP handles both congestion and flow control ⇒ True.
S2:
UDP handles congestion but not flow control ⇒ False, because UDP neither handles congestion control nor flow control.
S3:
Fast retransmits deals with congestion but not flow control ⇒ True.
S4:
Slow start mechanism deals with both congestion and flow control ⇒ False, because it has nothing to do with flow control. Flow control is taken care by Advertisement window.
