Open Systems Interconnection

The Open Systems Interconnection (OSI) model is a framework that standardizes how different computer systems communicate over a network. It divides the communication process into seven layers, each with specific functions, ranging from physical transmission of data to application services. This layered approach helps ensure that diverse systems can work together effectively, enabling tasks like sending emails or browsing the web. By separating functions, the OSI model promotes interoperability and simplifies troubleshooting, making it easier for developers and engineers to design and maintain complex networking systems.
