Many people ask: What’s the real difference between a Layer 2 and a Layer 3 switch?

✅ Layer 2 Switch

-Works with MAC addresses
-Sends data within the same network (LAN)
-Does not support routing between networks
-Used for connecting devices like PCs and printers in the same VLAN

✅ Layer 3 Switch

-Works with IP addresses and MAC addresses
-Can route data between different networks or VLANs
-Combines the speed of a switch with the routing ability of a router
