Explain the difference between layer 2 and layer 3 networking protocols.

Explaining the Difference Between Layer 2 and Layer 3 Networking Protocols:

Layer 2 and Layer 3 networking protocols are essential components of network communication. The focus keyword here is "difference between layer 2 and layer 3 networking protocols."

Layer 2: Also known as the Data Link layer, Layer 2 operates at the MAC address level. It is responsible for framing data into frames and sending them across a local network. Common Layer 2 protocols include Ethernet and Wi-Fi. Layer 2 does not involve IP addresses or routing.

Layer 3: The Network layer, Layer 3 operates at the IP address level and is responsible for logical addressing and routing data between different networks. Layer 3 protocols include IP, ICMP, and routing protocols like OSPF and BGP. Unlike Layer 2, Layer 3 protocols can reach across different networks and facilitate end-to-end communication.

Overall, the key difference between Layer 2 and Layer 3 networking protocols lies in their functions and scope of operation. Layer 2 focuses on local network communication at the MAC address level, while Layer 3 enables communication between different networks using IP addresses and routing.
