Question

What is hub used for in a network?

• A. Filtering Data
• B. Unicasting Data
• C. Multicasting Data
• D. Broadcasting Data

Hint:

Remember:
- Hub = Broadcasts everything (Insecure and low efficiency)
- Switch = Unicasts to destination (Learns MAC addresses, high efficiency)

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
A hub is a basic networking device operating at the physical layer (Layer 1) of the OSI model. It lacks the intelligence to identify the destination of data packets.

Step 2: Detailed Explanation:
When a hub receives a data frame from one port, it blindly transmits (broadcasts) the data to all other ports. It does not perform filtering, unicasting, or multicasting.

Step 3: Final Answer:
A hub is used for broadcasting data to all connected devices.
