What is L2/L3 protocols?

L2/L3 protocols refer to network protocols operating at Layer 2 (Data Link Layer) and Layer 3 (Network Layer) of the OSI model. Layer 2 protocols, such as Ethernet and Wi-Fi, handle data transfer between adjacent nodes on a network, typically within a local area network (LAN). They use MAC addresses for addressing. Layer 3 protocols, such as IP (Internet Protocol), handle routing data packets between different networks. They use IP addresses for addressing and are essential for internet connectivity. Common uses include network communication, internet access, and network segmentation.
