OSI (Open Systems Interconnection)
The OSI (Open Systems Interconnection) model is a framework that standardizes how different computer systems communicate over networks. It divides this communication process into seven layers, each serving a specific function, from physical transmission of data to application-level interactions. These layers help ensure that devices from different manufacturers can work together smoothly. The model promotes interoperability by defining protocols and standards for each layer, making it easier to develop and troubleshoot networking technologies. In essence, the OSI model serves as a blueprint for understanding and managing network communications.
