The fundamental distinction between a Layer 2 switch and a router is the network layer at which they operate.
A Layer 2 switch operates at the data link layer (Layer 2) of the OSI model. It uses MAC addresses to forward data packets within a local area network (LAN). Switches make forwarding decisions based on the MAC addresses in the Ethernet frame headers, allowing them to efficiently switch packets between connected devices in a LAN.
On the other hand, a router operates at the network layer (Layer 3) of the OSI model. It uses IP addresses to forward data packets between different networks. Routers examine the IP header of each packet and make routing decisions based on the destination IP address. They can connect multiple networks together and direct traffic between them, allowing devices from different networks to communicate with each other.
In summary, Layer 2 switches operate at the data link layer and forward packets based on MAC addresses within a LAN, while routers operate at the network layer and use IP addresses to route packets between different networks.
