Q: 1. What is the OSI reference model explain?

Answer: The OSI Model (Open Systems Interconnection Model) is a conceptual framework used to describe the functions of a networking system. The OSI model characterizes computing functions into a universal set of rules and requirements in order to support interoperability between different products and software.

Q: 2. What is the 7 layer OSI model?

Answer: The 7 layers of the OSI model. The layers are: Layer 1—Physical; Layer 2—Data Link; Layer 3—Network; Layer 4—Transport; Layer 5—Session; Layer 6—Presentation; Layer 7—Application.

Q: 3. What are the 5 types of OSI data?

Answer: In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Q: 4. What is the purpose of a reference model?

Answer: A reference model typically is intended to promote understanding a class of problems, not specific solutions for those problems. As such, it must assist the practitioner by aiding the process of imagining and evaluating a variety of potential solutions.

Q: 5. Why did the OSI model fail?

Answer: One reason that OSI failed was that it attempted to standardize everything. With little operational experience to guide them, the standardization groups added more and more features. The early Internet was much more pragmatic.
