Which of the following layers of the Open Systems Interconnection (OSI) networkmodel routes packets between devices? (Select the best answer.)

Question

Starting with a broad view of the OSI model helps place each layer in context. The question asks which layer is responsible for routing packets between devices, which points us toward Layer 3 concepts.
Option A: 'A. the Data Link layer' — This layer is mainly concerned with node-to-node data transfer across a physical link, framing, and error detection on that link. It does not conduct routing between networks, so this is not the layer that handles inter-network packet routing.
Option B: 'B. the Session layer' — The Session layer manages dialogues, control connections, and synchronization between software processes. It does not perform routing or forwarding of packets between devices, so this choice misplaces the routing function.
Option C: 'C. the Network layer' — This layer is tasked with logical addressing and routing packets across multiple networks, enabling inter-network communication. Routers operate at this layer to determine paths from source to destination, which aligns with the concept of routing between devices.
Option D: 'D. the Transport layer' — The Transport layer provides end-to-end communication reliability and flow control (e.g., TCP/UDP), but it does not handle the routing of packets between devices or networks. Its scope is end-to-end rather than network-wide routing.
In summary, the routing of packets between devices across networks is a function of the Network layer, not the Data Link, Session, or Transport layers. The Network layer handles logical addressing and path selection, enabling inter-network communication through devices like routers.
