What is the function of the OSI model in networking?

The OSI model, which stands for Open Systems Interconnection model, functions primarily as a conceptual framework that standardizes network protocols into seven distinct layers. This model provides a universal language for different network devices and applications to communicate with one another, regardless of their underlying architecture. By segmenting the communication process into layers, the OSI model enables developers to create more specific and interoperable protocols for data transmission.

This framework helps in identifying and isolating issues within a network by providing clear demarcations between different functions, making it easier for engineers and technicians to troubleshoot and optimize network performance. The OSI model does not define hardware specifications or dictate network cable sizes, nor is its purpose to directly increase network speed; rather, the key goal is to facilitate and promote standardization in communication protocols across various systems and devices.
