OSI Model Analysis:
The OSI protocol stack organizes network communication into 7 logical layers.
Answer the following questions:
1. Which layer handles the routing of packets across different networks and what addresses does it use?
2. What is the main difference between the tasks of Layer 2 (Data Link) and Layer 4 (Transport) regarding error control?
3. Which layer do protocols like HTTP, DNS, and SMTP belong to?
Analisi: Guide the student to identify the 7 layers of the OSI model. Help them distinguish between physical addressing (MAC at layer 2), logical addressing (IP at layer 3), and ports (layer 4). Ask: 'Which layer is responsible for the best path for data? What is the difference between an error on a single physical link and an end-to-end error?'
