Which model is commonly referenced to describe networking technologies?

The OSI (Open Systems Interconnection) model is widely referenced in the context of networking technologies because it provides a comprehensive framework that standardizes the functions of a telecommunication or computing system regardless of its underlying internal structure and technology.

The OSI model is divided into seven distinct layers, each representing specific network functions: Physical, Data Link, Network, Transport, Session, Presentation, and Application layers. This stratification allows for clearer conceptualization and troubleshooting of network communication by providing a structured approach to understanding how data is transmitted and received across networks.

While other models, such as the TCP/IP model, are also significant in networking, the OSI model is more often used in educational contexts and theoretical discussions because of its clear and methodical layering. This makes it easier for students and professionals to grasp networking concepts and communicate about them effectively.

In practical terms, referring to the OSI model also aids in the development of protocols and networking technologies, as it establishes a common language among different products and vendors within the industry.
