OSI Model
The Open Systems Interconnection (OSI) model is a classic seven-layer conceptual framework used for teaching network communications. From the physical signals at the bottom to the user software at the top, its seven layers are Physical, Data Link, Network, Transport, Session, Presentation, and Application.

In a layered network architecture, each layer executes a dedicated task and relies on the layer directly ___ it.
Based on the principles of layered network architecture, explain why the engineer can update this layer on its own, and state what dependency relationship governs this layer's operation.
