Open Systems Interconnect

The Open Systems Interconnection (OSI) model is a framework used to understand and standardize how different networking systems communicate with each other. It divides the communication process into seven distinct layers, each with specific functions—from the physical connection of devices to how data is presented and interpreted. This helps ensure interoperability among diverse systems and technologies by providing a common reference. In essence, the OSI model helps clarify the roles of various networking components, making it easier for engineers and developers to design and troubleshoot networks.
