Explanation:
The Transmission Control Protocol/Internet Protocol (TCP/IP) model is a standard networking protocol which allows network devices such as routers, switches, and host computers to interconnect and communicate with one another over a network. The Transmission Control Protocol/Internet Protocol (TCP/IP) model comprises of four (4) layers and these includes;
I. Application layer. 
II. Transport layer. 
III. Internet layer. 
IV. Network layer. 
The network layer in the Transmission Control Protocol/Internet Protocol (TCP/IP) model is responsible for delivering data between two nodes.
Basically, this layer known as network layer is the fourth layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model and it is typically responsible for the transmission of packets from one network device to another.
