A process's ID is 5988, what does the following command do? ps -o ppid= -p 5988 and ps -o ppid= -p 5988 a) Display the state of this process b) Display the memory usage of this process c) Display the child processes of this process d) Display the parent process of this process

Semaphores: Select all of the following statements that are true. The operations P (Test) and V (Signal) can be interrupted. The operations P (Test) and V (Signal) run in the operating system's user mode. The values of binary semaphores are restricted to 0 and 1. Counting semaphores are used to manage limited resources and the corresponding access to them. Semaphores can be used to synchronize certain operations between processes. When accessing the list of a semaphore, the FIFO principle should be preferred to the LIFO principle.

Consider the following code snippet: waitpid(-1, &status, 0); Which of the following correctly describes the purpose of this code snippet? it is equivalent to wait(&status); it causes the parent process to wait for the child process that terminates first and fetch that child's termination status it causes the parent process to wait for the child process whose pid is -1 and fetch that child's termination status The first two choices are both correct None of the above choices are correct Which of the following statements about wait(2) and waitpid(2) are true? The waitpid(2) function can block the caller until a child process terminates, whereas wait(2) has an option that prevents it from blocking. The wait(2) function doesn't wait for the child that terminates first; it has a number of options that control which process it waits for. If a child has already terminated and is a zombie, wait(2) returns immediately with that child's status. Otherwise, it blocks the caller until a child…

Why should a process exception be generated at this point?

This exercise involves designing a help-desk priority manager. Helprequests are stored in a text file with the following structure: priority, idof requesting party, time of request The priority is an integer in the range1–5 with 1 being the least important and 5 being the most important.The id is a four-digit employee identification number and the time is inTimeSpan.Hours, TimeSpan.Minutes, TimeSpan.Seconds format. Write aWindows application that, during the Form˙Load event, reads five recordsfrom the data file containing help requests, prioritizes the list using a priority queue, and displays the list in a list box. Each time a job is completed,the user can click on the job in the list box to remove it. When all five jobsare completed, the application should automatically read five more datarecords, prioritize them, and display them in the list box

Your application will demonstrate the ability to retrieve 10 numbers from a user and determine the smallest and largest number from the list. Incorporate the following requirements into your application: The program will consist of one file - the main application class Name the class appropriately and name the file Program.cs Include documentation at the top of the file that includes Your name Date of development Assignment (e.g., CIS214 Midterm Practical Exam) Description of the class The main application class must meet the following requirements Print a line that states "Your Name - Midterm Practical Exam" Get 10 integer values from the user and store them in an array or a List Write a method to determine the smallest element in the collection Write a method to determine the largest element in the collection Display the following information for the collection All the elements in the collection and the index of the element (displayed in columns as shown in the example…

This is a debugging problem - The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly. I have edited some of the code but I am unsure how to fix the rest -    // Application lists valid shipping codes // then prompts user for a code // Application accepts a shipping code // and determines if it is valid import java.util.*; public class DebugEight1 {    public static void main(String args[])    {       Scanner input = new Scanner(System.in);       char userCode;       String entry, message;       boolean found = false;       char[] okayCodes = {'A','C','T','H'};       StringBuffer prompt = new              StringBuffer("Enter shipping code for this delivery\nValid codes are: ");       for(int x = 0; x < okayCodes.length; ++x)       {           prompt.append(okayCodes[x]);           if(x != (okayCodes.length - 1))…
