The OSI Model (Open Systems Interconnection Model)

The OSI Model is a framework that helps understand how data travels across networks. It divides the process into seven layers, each with a specific role: from physical transmission (like cables) to ensuring data is accurate and correctly received. Think of it as a layered blueprint where each step, from sending data out of a device to its arrival and interpretation on another device, is managed systematically. This structure helps different devices and software communicate smoothly, even if they are made by different manufacturers, by standardizing how data is handled at each stage.
