OSI

Overview Network communication involves complex processes, and understanding these processes systematically requires a standardized reference model. The OSI (Open Systems Interconnection) 7-layer model is a network communication standard published by the International Organization for Standardization (ISO) in 1984. It divides communication between different systems into seven layers, defining how each layer operates independently while cooperating with others to transmit data. This model serves as a fundamental conceptual framework for network engineers and software developers to understand complex communication processes and diagnose problems. ...
