What is L2/L3 network protocols?

L2/L3 network protocols define how data is transmitted and routed across networks. Layer 2 (Data Link Layer) protocols like Ethernet and Wi-Fi handle communication within a local network, using MAC addresses for identification. Layer 3 (Network Layer) protocols, primarily IP (Internet Protocol), manage communication between different networks, using IP addresses for routing packets across the internet. Together, they enable seamless data transfer from one device to another, regardless of network boundaries. L2 protocols handle frame forwarding within a network and L3 protocols handle packet routing between networks.
