Question 1:  How do the layers of the Internet model correlate to the layers of the OSI model?
Question 2:  Match the following to one or more layers of the OSI model: a. Format and code conversion services b. Establishes, manages, and terminates sessions c. Ensures reliable transmission of data d. Log-in and log-out procedures e. Provides independence from differences in data representation
Question 3:  What is the difference between a port address, a logical address, and a physical address? How and at which layer they are used?
How do the layers of the Internet model correlate to the layers of the OSI model?
The Internet Model is a subset of OSI model.
OSI model consist of 7 layers.
7. Application Layer
6. Presentation Layer
5. Session Layer
4. Transport Layer
3. Network Layer
2. Data Link Layer
1. Physical Layer
But the Internet model consist of only 4 layers , where the 6th (Presentation Layer) and 5th(Session Layer) are combined with the Application Layer and finally the 1st (Physical Layer) and 2nd (Data Link Layer) are merged into a new NETWORK INTERFACE Layer.
