Which of the following statements about a hub in a star topology is true?
-
A.
It prevents collisions.
-
B.
It forwards data to all connected devices.
-
C.
It improves network security.
-
D.
It filters traffic based on MAC addresses.
Correct Answer:
B. It forwards data to all connected devices.
Explanation:
In a star topology, a hub acts as a central connection point that lacks the intelligence to direct traffic to specific destinations. When it receives a data packet from one node, it automatically broadcasts that information to every other device connected to its ports. This behavior distinguishes it from more advanced networking hardware, such as switches, which can filter and forward data specifically to the intended recipient based on MAC addresses. Consequently, while a hub facilitates basic connectivity, it does not enhance security or prevent data collisions effectively.
