Explanation:
ICMP or internet control message protocol is an Internet layer protocol in the TCP/IP suite. It works together with routing devices like the router to send messages based on results sensed in the network.

Answer:
There are different kinds of operating systems: such as Windows, Linux and Mac OS
There are also different versions of these operating systems, e.g. Windows 7, 8 and 10
Operating systems can be used with different user interfaces (UI): text user interfaces (TUI) and graphical user interfaces (GUI) as examples
Graphical user interfaces have many similarities in different operating systems: such as the start menu, desktop etc.
When you can recognize the typical parts of each operating system’s user interface, you will mostly be able to use both Windows and Linux as well as e.g. Mac OS.

the installation and use of programs, and
the handling of files.
Based on my personal experience in the workforce, all of the above would be the correct answer. That's based off my experience though. Owners would regularly come in and talk to our managers and employees to make sure everything was kept in order and in compliance. The only other answer I could see fit would be supervisors. Hope I was able to help :)
