Explanation of Layer 2 vs Layer 3 in Networking

Layer 2 and layer 3 are different levels of the OSI model that play crucial roles in networking.

Layer 2 - Data Link Layer

Layer 2, also known as the Data Link Layer, operates on MAC addresses and is responsible for the physical addressing and direct point-to-point connections in a network.

Layer 3 - Network Layer

Layer 3, the Network Layer, works with IP addresses and focuses on routing and logical addressing to facilitate communication between different networks.

While layer 2 deals with local connections within a network, layer 3 enables communication between separate networks by determining the best path for data packets to reach their destination.

Understanding the distinction between layer 2 and layer 3 is essential for network administrators to effectively manage and troubleshoot network issues.
