Technical Example
"The first of the seven layers of the OSI reference model, from the user's perspective, are application, presentation, and session, which are the software layers. The next layer is transport, which is the fundamental layer of the OSI model. The final layers, known as the hardware, are network, data link, and physical. These are the layers a computer network architect focuses on. Each layer has a specific function and moves a specific type of data using technologies related to the layer."
