According to the US National Institute of Standards and Technology, the TCP/IP stack is split into four different layers: applications, transport, IP and hardware.
The application layer sends and receives data for particular application such as DNS. The transport layer provides connection-oriented or connectionless services for transporting application layer services between networks.
The IP layer routes packets across networks. Lastly, the hardware layer handles communications on the physical network components.
