- It divides the network communication process into smaller and simpler components,
- thus aiding in component development, design, and troubleshooting.
It allows multiple-vendor development through the standardization of network components.
It encourages industry standardization by defining what functions occur at each layer of the model.
It allows various types of network hardware and software to communicate.
It prevents changes in one layer from affecting other layers, so it does not hamper development.
