In packet-switched environments, routers and switches will make decisions on the best route for a packet to take. This is why different packets of a message can arrive out of order, as they did not necessarily all follow the same path. What technology do these types of protocols use to make the path decisions?
A.
Time Division Multiplexing
B.
Carrier Sensing Multiple Access
C.
Statistical Time Division Multiplexing
D.
Frequency Division Multiplexing
Explanation:
Packet switching is based on Statistical Time Division Multiplexing
(STDM), which analyzes statistics on the various possible routes to make the
decision on the best route for a packet.
