Open Systems Interconnection Basic Reference Model

The Open Systems Interconnection (OSI) Basic Reference Model is a framework that organizes how different computer systems communicate over a network. It divides the process into seven layers, each handling specific tasks—like transmitting data, ensuring it arrives intact, and presenting it in a readable format. By standardizing these layers, devices from different manufacturers can understand each other and work together seamlessly. This model helps in designing, troubleshooting, and understanding complex networks by breaking down the communication process into manageable, well-defined steps.
