OSI Models

The OSI Model is a conceptual framework that standardizes the functions of a communication system into seven distinct categories, or layers. Coursera's OSI Models catalogue teaches you about this fundamental aspect of networking, which is crucial for understanding how data is sent and received over networks. You'll delve into each of the seven layers - Physical, Data Link, Network, Transport, Session, Presentation, and Application - understanding their roles and how they interact with each other. You'll develop a comprehensive understanding of networking protocols, data encapsulation, and the principles of network communication. This skill is essential for roles such as network engineers, system administrators, and IT professionals aiming to deepen their understanding of network architecture and operations.
