What is the purpose of the OSI Model?

The purpose of the OSI Model is to provide a framework for understanding network communication. This model divides the complex process of network communication into seven distinct layers, each with specific functions and responsibilities. By doing so, the OSI Model creates a standard that facilitates communication across diverse systems and networks, allowing different technologies to interact effectively.

Each of the seven layers—Application, Presentation, Session, Transport, Network, Data Link, and Physical—plays a crucial role in the transmission of data. This layered approach not only aids in troubleshooting and designing network systems but also enhances interoperability among various networking protocols and hardware. As a result, the OSI Model serves as a universal reference that helps network professionals conceptualize how data travels from one point to another, thus simplifying the complexities of networking.

Other options focus on different aspects of networking: defining hardware standards, measuring performance, or ensuring security, which are not the primary goals of the OSI Model. Instead, the OSI Model's strength lies in its ability to abstract and organize the functions of networking into manageable components, fostering a deeper understanding of how networks operate.
