The OSI model was designed by network professionals to usefully pull apart the different layers of a very complex system so the various elements of that system can be better understood by those who are learning about data networks for the first time, and for teachers who would otherwise struggle to pull all of the pieces together to teach the whole system. This framework organizes the process of understanding networking fundamentals into seven distinct layers, each with a specific purpose and role, creating a clear and logical pathway for understanding how devices connect and exchange data.
