Networking Conceptual Models

Networking conceptual models are structured frameworks that standardize how different computer systems communicate and work together. The most common model, the OSI (Open Systems Interconnection), divides communication into seven layers, from physical connections to how data is presented and understood. This helps ensure devices, regardless of manufacturer, can exchange information smoothly. Think of it like a layered recipe: each layer has specific roles, making troubleshooting, design, and development more organized. These models don’t describe specific hardware but serve as blueprints to ensure systems can connect, share data, and function effectively across diverse networks.
