How does a switch differentiate from a hub in terms of data transmission?
- A switch broadcasts data to all connected devices.
- A switch forwards data based on IP addresses.
- A switch forwards data based on MAC addresses.
- A switch sends data to all devices except the source.
A switch operates at the data link layer (Layer 2) of the OSI model and uses MAC addresses to make forwarding decisions. It forwards data only to the specific device associated with the destination MAC address, making it more efficient than a hub.
