Step by step
Solved in 5 steps
- There is a thorough explanation of the differences between network architecture and application architecture.In the OSI model, three layers divide the application layer from the network layer: presentation, session, and transport. The application layer is closest to the end user and the network layer is closest to the physical network. Based on the functions of the three layers between application and network, how do you anticipate the implementation of these layers changes from application to network, as information is moved from one layer to another? What is the importance of understanding the functions of these layers? How are layers represented in the TCP/IP model?What is the role of the Transport layer in the OSI model and what are its key functions?
- Analyze the benefits and challenges of implementing Network Function Virtualization (NFV) across various OSI model layers in modern network architectures.What is the role of a hub in the OSI model, and how does it operate at the physical layer?Describe the seven levels of the OSI model, the seven sublayers within those levels, and the protocols that are used at each level.
