We often hear of these two terms and try to distinguish them, which one is better for building our network 
To be simple, Layer 3 switches route packets based on IP, layer 2 by MAC. Both switch types have the capability of linking network devices together from one port to another. Unlike hubs, switches distribute data more intelligently as it interprets them and sends it out to the right destination.
Layer 2 and Layer 3 terms come from the OSI seven Layer model (a theoretical way of dividing network architecture up with functionality, service, dependence and application). Within the model, Layer 2 represents the “Data Link Layer” while Layer 3 represents the “Network Layer”.
Layer 2 switches have the capability of mov
ing packets around a single network. As the reference to the OSI Layer holds true, this
