A comprehensive overview of the osi (open systems interconnection) model, which is a conceptual framework used to describe the functions of a networking system. The various layers of the osi model, including the physical, data link, network, transport, session, presentation, and application layers, and explains the specific functions and protocols associated with each layer. The document also includes a series of verified questions and answers related to the osi model, which can be used to test one's understanding of the concepts. This resource would be particularly useful for students and professionals studying or working in the field of computer networking, as it provides a solid foundation for understanding the underlying principles of network communication and the role of the osi model in facilitating this process.
