- For each of the following isolation levels, give an example of a schedule that respects the specified level of isolation but is not serializable: a. Read uncommitted b. Read committed c. Repeatable readProblem: Implement a part of functionality for the Netflix DVD queue. It's a service that allows a user to create a list of desired movies and then sends DVDs with movies on top (what we called head in our lectures) of this list to the subscriber one at a time. A subscriber should be able to create a list of desired movies and manipulate the order in a movie queue in their account. Your program will implement some of the desired functionality by storing the list of movie titles in a linked list. You are provided with the following files available in the "Downloadable files" section: MovieList.h contains a class declaration for the class that represents a list of movies. top refers to the head position of a list and bottom refers to the tail or end position of a list. Driver.cpp contains the main function you can use to test your implementation. *** NOTE: Please do not change any of the function names since our automated test script calls those functions. Changing function names or…The following question is related to Threading in C programming Task-3: Write a program in c that has a function that takes the name of the user and adds all the ASCII value of the characters and returns it. Now create 3 threads that run the function using 3 different user names. Now print “Youreka” if all the returned values are equal, print “Miracle” if the 2 returned values are equal, and print “Hasta la vista” if the values don’t match using another thread.
- In this project you are to design a process queue that is responsible for handling the process requests coming from different users. You have to take into consideration that users have different levels of privileges and priorities. Each user has an identification number and a password, in addition to process priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every process request received, the program should check the privileges of that request and whether it can be moved forward in the queue to be served by the operating system prior to serving the other requests. Using the programming language of your choice (preferably C+), write the process queue that would handle the user request. The program must allow for requests coming from different users or from one user.Problem: Implement a part of functionality for the Netflix DVD queue.
