Question
HUB is a ……... Device and Switch is a ………. Devicea.Unicast, Multicastb.Broadcast, Unicastc.Multicast, Unicastd.None of the above
Solution
The correct answer is b. Broadcast, Unicast.
Here's why:
-
A Hub is a Broadcast device: When a data packet arrives at one port, it is copied to all other ports so all segments of the LAN can see all packets. This means it broadcasts the data it receives.
-
A Switch is a Unicast device: It has the ability to learn and distinguish between specific addresses by accessing them from a media access control (MAC) address table. This means it can direct the data it receives to a specific device, hence it unicasts the data.
