d. Firewall

Respuesta :

The highest layer accessed by each of the following devices are:-

Router: Network/internet  layer.

Unmanaged switch: Application layer

Wireless access point:Application layer

Firewall: Transport layer and the Network layer

Explanation:

TCP/IP stands for Transmission Control Protocol/ Internet Protocol

The TCP/IP networking model has four layers, namely,

  1. Application layer
  2. Transport layer.
  3. Internet layer .
  4. Network interface layer.

  2. Transport Layer: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.
  3. Internet Layer: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.
