WHAT IS OSI MODEL The OSI open network reference model or the OSI Reference Model for open networks is a network architecture model developed by the International Organization for Standardization (ISO) in Europe in 1977. Open systems interconnection or OSI created in the form of a conceptual framework. Even now it has become a standard connection for a computer. Moreover, it was created to fulfil a specific purpose. The goal is that the OSI model becomes a reference for each vendor or developer so that the software and products they make have interpolated properties. This means that users do not need to make special efforts and they can collaborate with the system or product. In OSI itself, there are 7 layers and each of them has its own function namely physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer.
