Layer 2 (Data Link Layer)

Layer 2, or the Data Link Layer, is the second level in the OSI model of computer networking. It is responsible for establishing, managing, and terminating connections between devices on the same network. This layer ensures that data packets are correctly framed for transmission, detects errors, and manages access to the shared physical medium, like wires or wireless channels. By handling these tasks, Layer 2 enables devices to communicate efficiently and reliably, ensuring that the information reaches its destination without corruption.
