What does the OSI Model help to understand in networking?

The OSI Model, which stands for Open Systems Interconnection Model, is a conceptual framework that helps to understand and standardize the functions of a networking system by dividing the communication processes into seven distinct layers. Each layer has its own specific function and communicates with the layers directly above and below it, allowing for modularization in network design and troubleshooting. By understanding these layers, network professionals can effectively diagnose issues, develop solutions, and build systems that adhere to standardized protocols, making it easier to ensure compatibility between different technologies and vendors.

This layered approach not only clarifies the roles of different network protocols but also aids in understanding how data travels from one device to another across a network. Each layer of the model handles specific aspects of the communication process, such as data formatting, addressing, and error handling, offering a comprehensive view of the networking landscape.
