OSI Model
The Open Systems Interconnection (OSI) model is a classic seven-layer conceptual framework used for teaching network communication. Structured from physical transmission signals at the bottom to end-user applications at the top, its layers comprise: Physical (cables, radio waves, and voltages), Data Link (communication between directly connected devices using MAC addresses), Network (routing packets across multiple networks using IP addresses), Transport (end-to-end delivery between programs via TCP and UDP), Session (managing ongoing application conversations), Presentation (formatting and encrypting data), and Application (software interactions such as web browsers and email).

In a modular layered network model, modifying or updating an individual layer requires re-engineering the entire network stack simultaneously.
An engineering team is planning to update an individual protocol layer in their network stack. Based on the principles of modular layered network architecture, explain how this update can occur independently. In your explanation, be sure to address:
- The overarching purpose of structuring network systems into modular layers.
- The functional dependency between the layer being updated and the layer immediately beneath it.
- Why the updated layer must continue to fulfill its dedicated function

In the OSI model framework, end-user applications are located at the bottom while physical transmission signals are positioned at the top.
Compare the Data Link layer and Network layer of the OSI model by identifying the scope of communication and the specific addressing type used by each.
Match each OSI layer to its primary role or examples as defined in the framework.
In the OSI model, managing ongoing application conversations is the role of the ___ layer.
Order these lower layers of the OSI model from the bottom (physical transmission) toward the higher layers.
