10. OSI MODEL The Open Systems Interconnection model is a reference model from the International Organization for Standardization that "provides a common basis for the coordination of standards development for the purpose of systems interconnection .

11. SESSION LAYER The Session Layer is the 5th layer in the Open System Interconnection (OSI) model. This layer allows users on different machines to establish active communications sessions between them. It is responsible for establishing, maintaining, synchronizing, terminating sessions between end-user applications. In Session Layer, streams of data are received and further marked, which is then resynchronized properly, so that the ends of the messages are not cut initially and further data loss is avoided.
