Answer:

You're talking about the network layer of the OSI model, which is the fourth layer in the model. This layer provides the protocols and services needed to connect a device to the internet. The network layer includes the protocols that allow data to be transmitted and received between devices. For smartphones, the network layer includes the cellular network technology that connects the device to the internet, such as 4G or 5G. Is that the answer you were looking for?
