The highest layer accessed by each of the following devices are:-
Router: <u>Network/internet layer.</u>
Unmanaged switch: <u>Application layer</u>
Wireless access point:<u>Application layer</u>
Firewall: <u>Transport layer and the Network layer</u>
Explanation:
TCP/IP stands for Transmission Control Protocol/ Internet Protocol
The TCP/IP networking model has four layers, namely,
- <u>Application layer</u>
- <u>Transport layer.</u>
- <u>Internet layer .</u>
- <u>Network interface layer.</u>
- <u>Application layer:</u>This is the highest layer or level of the OSI Model.It allows the user to interact with the software applications.
- <u>Transport Layer:</u>This layer builds on the network layer to transfer data from a process on a source system machine to a process on a destination system.
- <u>Internet Layer:</u>This layer is also known as the network layer.It is responsible for the transportation of Packets from any network or computer irrespective of the route it takes.
- <u>Network interface Layer:</u> This layer is also called a network access layer. It helps you to defines details of how data should be sent using the network.
