Show answer & explanation
Correct answer: B
Answer: Only statement II is not true.
Statement I: True. In a star topology all devices connect to a central device (hub or switch); if that central device fails, the network becomes nonfunctional.
Statement II: False. Each device has a dedicated point-to-point link to the central device, so adding more computers does not inherently increase the communication time per link. (Caveat: overall throughput can be affected if the central device becomes overloaded, but that does not make the statement generally true.)
Therefore, the correct choice is that only statement II is not true.
