1. How does using the OSI model facilitate teaching and learning about networking?
Although most modern networks do not implement the OSI model exactly as it is defined, the model remain an excellent reference and learning tool. The OSI model is broken down in seven layers so you can understanding the proccess


2. How does using the OSI model facilitate the development of networkinh hardware and software?
The model allows programmers to concentrate on one layer.


3. How does using the OSI model provide compatibility and standardization between networking products? The OSI model was developed as an industry standard for companies to use when developing network hardware and software to ensure complete compatibility. Each layer in the OSI model performs



4. How does the user fit into the OSI model?
You can not fit into the OSI model.

5. What is the importance of the Network Layer? The Network layer routes data and provides connectivity to remote networks using the best path. the Network layer contains software-addressing information for data packets, which makes network segmentation and routing possible. It allows communication.



6. At which layer do the ultimate sender and receiver of data make contact?
The Transport Layer.


7. If you are browsing the Web and the networking cable gets pulled out of the computer, the connection to the Web site can often be restored if you plug the cable back in. Which layer is responsible for maintaining the connection?
Session Layer 5


8. What are the two sublayers of the Data Link layer? Which one is closer to the Physical layer?
Logical Link Control layer (LLC) and Media Access Control layer (MAC) , Media Access Control Layer


9. What is meant by "peer communication" with respect to the OSI model? Each layer will only talk to its peer on the opposite side of the communications process.



10. Is networking software more closely related to the upper layers of the OSI mode? upper layers
