Explanation:
There are ethical responsibilities that must be linked to the use of technological systems by computer professionals in relation to the protection of the privacy rights of their fellow citizens.
Exercising ethical behavior is essential for computing to be used for its central benefits, which is to make life and tasks simpler and more dynamic, and not for technical knowledge about computer science to be used for personal or other benefits. , therefore, it is ideal that there is ethical responsibility for computer professionals so that ethical decisions are taken so that knowledge is used for the benefit of society and not to commit illegal acts.

The router whose main function is to route packets across the network is also used to connect between LANs and between LAN and a WAN.
The firewall is typically installed on systems or in servers or in routers with it most important function to filtering the traffic and minimize the packet delivery delay in LANs.
