Which OSI layer provides reliable transmission of frames between adjacent nodes and is built on top of the provides reliable transmission of frames adjacent nodes and is built on top of the Physical l

The Data Link layer (Layer 2) frames data for transmission, handles MAC addressing, and uses error detection mechanisms such as CRC to ensure reliable delivery between two nodes on the same network segment. It directly encapsulates data received from the Network layer and passes raw bits down to the Physical layer (Layer 1), making it the layer immediately above the Physical layer.

The Transport layer (Layer 4) provides end-to-end reliable transmission across multiple hops using protocols like TCP, not between adjacent nodes at the frame level.

The Network layer (Layer 3) handles logical addressing and routing of packets across different networks, operating above the Data Link layer.

The Application layer (Layer 7) provides network services directly to end-user applications and has no role in frame-level transmission between adjacent nodes.
