OSI Model (Open Systems Interconnection Model)

The OSI (Open Systems Interconnection) Model is a framework that organizes how different computer systems communicate over a network. It divides this process into seven layers, each responsible for specific tasks like sending data, ensuring it arrives correctly, and enabling applications to understand each other. Think of it like a multi-layered translator, helping devices from different manufacturers exchange information smoothly. This clear separation allows troubleshooting, development, and standardization, ensuring reliable and compatible network communication across diverse systems.
