Three part question.

Part A: On your Linux image, open a terminal and navigate to the $/$proc directory. Do an $"$ls$"$ and explain what the numbered directories represent $($think Chapter $3$ and look this up on the internet if required$).$

Part B: pick one of the numbered directories and cd into it$.$ Do an ls and explain what you see. What information do these files store?

Part C: In that same directory, do a "more sched". From the context $($pun intended$)$ of Chapter $3,$ explain nr$\_$switches, nr$\_$voluntary$\_$switches and nr$\_$involuntary$\_$switches.
