Difference in Switch and Hub

Question

Accepted Answer

Switch forwards data to specific devices based on MAC address, while hub broadcasts data to all devices on the network.

Switch operates at the data link layer (Layer 2) of the OSI model, while hub operates at the physical layer (Layer 1).
Switch is more efficient as it only sends data to the intended recipient, reducing network congestion.
Hub is a passive device that simply repeats incoming data to all connected devices, leading to potential security risks.
Example: A switch would be used in a network to connect multiple computers, while a hub would be used for connecting devices in a small home network.
