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…
Real-time Scheduling: Choose all true assertions. Rate Monotonic (RM) scheduling divides time into equal parts and requires each process to seek a portion upon starting. RM schedules real-time systems with CPU utilization below 1. When CPU utilization is less than 1, Earliest Deadline First (EDF) may schedule a real-time system. A process is initiated every p time unit. RM scheduling prioritizes shorter processes. EDF scheduling prioritizes processes with the shortest time frame.
Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int…
01. Please _Given an integer num, repeatedly add all its digits until the result has only one digit, and return it. Example 1: Input: num = 38 Output: 2 Explanation: The process is 38 --> 3 + 8 --> 11 11 --> 1 + 1 --> 2 Since 2 has only one digit, return it. Example 2: Input: num = 0 Output: 0 Constraints: 0 <= num <= 231 - 1 Follow up: Could you do it without any loop/recursion in O(1) runtime? //code here class Solution {public: int addDigits(int num) { }}; //.
The following program consists of 3 concurrent processes and 3 binary semaphores. The semaphores are initialized as S0 = 0,S1 = 1 and S2 = 1. Process P0:while (true) { wait (S0); print '1';release(S1);release(S2);} Process P1:wait (S2);release (S0); Process P2:wait(S2);release(S0); How many times will process P0 print '1'?
Basic deadlock questions: Select all of the following statements that are true. Reusable resources are produced and consumed dynamically. Interrupts, messages, and signals are examples of consumable resources. A deadlock means that at least two processes cannot continue working because they are waiting for each other. In order for a deadlock to occur only one of the four introduced deadlock conditions must apply. One of the four introduced deadlock conditions is non-preemption. A set of processes is in a safe state S if S is not a deadlock state and any state T reachable from S is not a deadlock state.
AWS Lambda Function-Python programming Using boto3 library, please give a code that can delete an elastic load balancer with no instance attached to the elastic load balancer Provide code/screenshot
A developer has written an AWS Lambda function. The function is CPU-bound. The developer wants to ensure that the function returns responses quickly. How can the developer improve the function's performance? O A. Increase the function's CPU core count. OB. Increase the function's memory. OC. Increase the function's reserved concurrency. OD. Increase the function's timeout.
Cooperating Processes: Select all of the following statements that are true. Ordinary (unnamed) pipes provide a solution for bidirectional communication between related processes. Mechanisms for inter-process communication enable different processes to exchange information and synchronize their actions. The bounded buffer solution to the producer-consumer problem, which was the first one discussed in class and does not use semaphores or monitors, allows at most BUFFERSIZE items in the buffer at the same time.
Bounded waiting requires that \A bound must exist on the number of times that other processes are allowed to enter their critical sections a) true b) false
Select all statements below that are true O A set of processes is in a safe state S if S is not a deadlock state and any state T reachable from S is not a deadlock state. In order for a deadlock to occur, only one of the four conditions necessary for deadlocks to occur must be satisfied. O A deadlock means that at least two processes cannot continue working because they are waiting for each to make resources available. о One of the the four conditions necessary for deadlocks to occur is non- preemption. Interrupts, messages, and signals are examples of consumable resources. Reusable resources are produced and consumed dynamically. QL - DELL W
