Overview of the OSI model

The OSI model is a framework (conceptual) that standardizes the functions of a telecommunication or computing system into seven distinct layers, with each layer representing a specific set of tasks and responsibilities. The model serves as a reference for understanding how different networking protocols and technologies interact with each other.

Before the OSI model, there were various proprietary networking architectures and protocols that lacked interoperability. This made it difficult for different vendors’ equipment and software to work together in a cohesive manner, hindering the growth and advancement of computer networking.

The model is devised to serve the purpose of the following:

  • Creating a level of standardization: The goal is to establish a common and consistent way of outlining network communication functions and interactions. Defining specific layers and their respective responsibilities provides a clear blueprint for networking...
