What is Internet Layer?

The internet layer is made up of the main data transmitting communication components that allow the internet to operate, such as the Transmission Control Protocol (TCP) and the Internet Protocol (IP). The internet layer, along with the link layer, are the layers that the rest of the internet are built on. While somewhat ambiguous, the internet layer typically attaches to routing systems, telecommunications infrastructure such as electronic circuits, the Ethernet, and networking centers that host and transmit much of the data that makes up the internet.
