![OSI Model The Open Systems Interconnection model (OSI Model) is a conceptual model that characterizes and standardizes thecommunication functions of a telecommunication or computing system without regard of their underlying internal structure and technology. Its goal is the interoperability of diverse communication systems with standard protocols. The model partitions a communication system into abstraction layers. The original version of the model defined seven layers.[WIKIPEDIA]](https://image.slidesharecdn.com/homework-networkworkshop-151106100425-lva1-app6891/75/Introduction-to-network-Internet-and-its-layer-Or-how-internet-really-works-4-2048.jpg)
