Answer / Praveen Kumar Upadhyay
"Switches are networking devices that forward data packets from one port to another based on the destination's MAC (Media Access Control) address. They operate at the Data Link Layer (Layer 2) of the OSI model.nnA Layer-3 switch extends this functionality by also examining the network layer (IP) addresses within the data packets and can route traffic between different subnets. This allows for more flexible networking configurations than traditional switches, making them an important component in many networks."
