Give an example for each of these macros to explain its work: Macro: int WIFSIGNALED (int status) This macro returns a nonzero value if the child process terminated because it received a signal that was not handled. Macro: int WTERMSIG (int status) If WIFSIGNALED is true of status, this macro returns the signal number of the signal that terminated the child process. Macro: int WCOREDUMP (int status) This macro returns a nonzero value if the child process terminated and produced a core dump. Macro: int WIFSTOPPED (int status) This macro returns a nonzero value if the child process is stopped. Macro: int WSTOPSIG (int status) If WIFSTOPPED is true of status, this macro returns the signal number of the signal that caused the child process to stop.

Question No: 06 This is a subjective question, hence you have to write your answer in the Text-Field given below. Consider P0,P1,P2 are three processes synchronised with semaphores S0=1,S1=0,S2=0 as shown initialised. The table below gives the code of the processes Process PO While (true) { Process PI Process P2 Wait(S2); print 1"; signal(S1), wait(S1); signal(S1); wait(so); print *0"; signal (S1); signal (S2); a If the sequence of processes schedule is P1,P2,P0,P0,P2,P0,P2,P0. What are the values printed? b. If the semaphores are initialised with S0-0,S1=1 ,S2=1. What are the values printed for the above sequence?
Critical Sections: Select all of the following statements that are true. A critical section is a segment of code in which a process has write-access to data or resources that are shared with at least one other process. In a system consisting of n processes, a critical section can be entered by more than one of these n processes at a time. In order to protect critical sections, race conditions are used in a process to request permission to enter its critical section. A process that is currently not executing in its critical section must not prevent other processes to enter the critical section. Every process waiting at the entrance of a critical section must be allowed to enter this section at some point. No eternal waiting must be possible. Mutual blocking is one method to decide which process may enter the critical section first.
C++ Assignment Setup Part 1: Working With Process IDs Modify the getProcessID() function in the file named Processes.cpp The function must find and store the process's own process id The function must return the process id to the calling program. Note that the function currently returns a default value of -1.Hint: search for “process id” in the “System Calls” section of the Linux manual. Part 2: Working With Multiple Processes Modify the createNewProcess() function in the file named Processes.cpp as follows: The child process must print the message I am a child process! The child process must then return a string with the message I am bored of my parent, switching programs now The parent process must print the message I just became a parent! The parent process must then wait until the child process terminates, at which point it must return a string with the message My child process just terminated! and then terminate itself. Hint: search for “wait for process” in…
Create a new C# project then write a code equivalent to solve the problem given below. Create a menu driven program that will perform the following operations specified below. The program shall request data needed and display the result accordingly. Operations: - ADD NEW DATA - INSERT DATA - UPDATE DATA - DELETE DATA - RESET - SHOW DATA - EXIT Operations: - ADD NEW DATA – request single data from the user and store to arraylist - INSERT DATA – request index location and data to be inserted - UPDATE DATA – request index location and data to be updated - DELETE DATA – request data to be deleted - RESET – clear or reset the elements of arraylist - SHOW DATA – display all the elements of arraylist in horizontal manner - EXIT – end the execution of the program

Part 3: JavaScript - Program Outline, Startup Function, and Prompt We are going to use a function that we can consider an entry point into our running JavaScript. Below is an outline of the major elements in our JavaScript file. getRandomInt() function: generate a random integer startup() function: entry point function call to startup() function Below is your startup code: function getRandomInt(min, max) {}function startup() {}startup(); >> Add the above code components to your cis111-07.js JavaScript file below your multiline comment. >> Copy the getRandomInt function code from your previous assignment, or from this Stackoverflow article (Links to an external site.). Remember to add a single line comment above the getRandomInt function that documents the source of the code. Before attempting to use the prompt function in your code, you should try out the function in the console. >> Enter the following into the console to test displaying the prompt dialog. prompt();…

Contiguous Memory Allocation Algorithms The program will read size of free memory partitions and size of processes from a text file and then will try to allocate a memory partition for each process using the first-fit, best-fit and worst-fit allocation algorithms. The implementation completed in Python programming language. The first line of the input file should contain the size of free memory partitions (in order) while the second line contains the size of processes (in order). Sample input file is shown below: 300,600,350,200,750,125 115,500,358,200,375 The program should read the name input file as command line input and produce a text file named “output.txt” with the following example output: First-Fit Memory Allocation ----------------------------------------------------------------------------------------------- start => 300 600 350 200 750 125 115 => 115* 185 600 350 200 750 125 500 => 115* 185 500* 100 350 200 750 125 358…
