OSI (Open System Interconnection) reference model was created by ISO (international Standard Organization) to create a standard for movement of internet traffic. It talks about all Seven Layers of OSI Model – Physical Layer, Data Link Layer, Network Layer, Transport Layer, Session Layer, Presentation Layer and Application Layer. The combination of all layers make OSI Model. It was create in 1984 and followed by all in network arena. I am creating these video after getting request from some of my friends and students. We will be creating appx 10 Video (each for one Layer) and sharing for knowledge.
