Network models and encapsulation

Definition and example

Network models and encapsulation is the focus of this lesson. Network models describe how data moves through layers. Encapsulation adds layer-specific information as data travels down the stack. Practice: Create a short note for ‘Network models and encapsulation’ in a local training document. Apply the idea to a fictional or deliberately provided sample, record what you checked, and note one limitation. Do not use real credentials, private records or systems without written permission. The task asks you to apply that idea in a small example: What does encapsulation do in network communication. Before you run the code, predict what should happen. Then Inspect the result produced by the exercise and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
