The OSI model, which stands for Open Systems Interconnection model, is designed to standardize networking protocols into layers, facilitating efficient communication between different systems. This layered approach divides networking roles into seven distinct layers, allowing various network hardware and software to interact in a predictable and consistent manner. Each layer addresses specific functions and allows developers to implement and troubleshoot networks in a modular fashion.

By adhering to the OSI model, developers and network engineers can ensure that products from different manufacturers can work together seamlessly. This standardization helps in creating environments where different communication protocols can coexist and interoperate effectively. For instance, when troubleshooting issues in communication, understanding which layer the problem resides in can greatly assist in diagnosing the issue.

In contrast, while creating a physical layout of networks or designating hardware types are important tasks in networking, they do not directly relate to the primary role of the OSI model. Additionally, though the model can provide some guidelines that might assist in troubleshooting, it is not primarily intended to serve as a troubleshooting guide. Its foundational goal is to set a clear framework for communication standards across various technologies and platforms.
