What is OSI Model | Real World Examples

This podcast delves into how data travels across the internet, using the OSI model as a guiding framework. The model consists of seven layers—Physical, Data Link, Network, Transport, Session, Presentation, and Application—which demonstrate the processes of encapsulating and decapsulating data during its journey. It specifically highlights TCP and UDP protocols within the Transport layer. Although the OSI model doesn't capture every nuance of real-world networking, it serves as a valuable educational tool and a concise way to describe network functions, especially regarding load balancers at layers 4 and 7.
