Answer:
Network.
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.
Answer:
B)tracert
Explanation:
Tracery Command can be regarded as
network diagnostic tool, it is used in tracking process of pathway of packet ranging from source to destination on IP network. It as well allows to know real time of each hops that are been taken by a packet as it enroutes to it's destination. The traceroute can be run by following these steps:
✓Open the run window
✓Open Command prompt, this can be done by enter "cmd" then enter.
