Show answer & explanation
Correct answer: A
In a star topology, every computer is connected to a central device such as a hub, switch, or central computer.
Statement I: Failure of the central computer/device shuts down the entire network.
This is true because the central device is the single point through which communication occurs. If it fails, nodes cannot communicate through the network.
Statement II: Connection of additional computers increases the communication time.
This is not true for star topology. A new computer is connected directly to the central device through its own link. Adding a node does not increase the path length between existing nodes.
The question asks for the statement(s) that are not true. Only Statement II is not true. Hence, Option A is correct.
