Explanation

In the OSI model, each layer uses a specific term for its Protocol Data Unit (PDU). At Layer 3 (Network), the PDU is called a 'packet.' At Layer 2 (Data Link), it's called a 'frame.' At Layer 4 (Transport), it's called a 'segment.' At Layer 1 (Physical), it's called 'bits.' The Network layer is responsible for logical addressing (IP) and routing, which is where packets are created and forwarded between networks. The Session layer (Layer 5) deals with establishing and managing sessions, not packets.
