What is OSI Model? OSI stands for Open Systems Interconnection and is a conceptual framework for how applications communicate over a network. There are seven layers within the model and the layers depiction is used to help users identify what is happening within a networking system. The OSI model layers are typically described from the top layer down. The layers are described as Application, Presentation, Session, Transport, Network, Data Link, and Physical. ✅ Check out the full blog post over a
