- If multiple threads are acquiring multiple locks, the order in which the threads attempt to acquire them makes no difference. True or FalseDeadlock: situation in which a set of threads/processes cannot proceed because each requires resources held by another member of the set. Select one: True FalseWhat is a race condition? Why is it undesirable when programming threads?
- Order the following for a thread's use of a shared resource. release lock use resource wait for lockMutual exclusion is act of allowing only one process to have access to a dedicated resource. Select one: O True O FalseWhy is it a good idea for a server to create threads to handle clients' requests?
- Must be Python code only You will display a line chart of a dynamic dataset. It is advised that you start with assignment 3 and add the capability to update the display you will add the capability of dynamically displaying a change dataset. You will build a GUI to display a set of values. You will display the values using both a line chart and a bar chart on the same app. Create a method that will be executed in a thread. This method will do the following in an infinite loop: Remove the first item in the list of values Add a new random value to the end of the list Call the method to display list on the canvas Sleep for a short while (0.5 of a second). In the initUI() method do the following at the end: You may remove the Entry widget. This is not used in this application. Create a thread and set the target to the method in step 1 Set the daemon property of the above thread to True. This will terminate the thread when the GUI closes. Start the thread. Modify the method that draws…Question: 1 Create 4 threads extending Thread class. Show the names of those threads. Rename them using proper method. Find out the default priorities they have and then set the priorities of them starting with zero. Like thread-0 will have priority 1. Then find the min and max priorities. Each of the threads needs to perform the following tasks. Thread-0 will print all the even numbers in between 1 and 100. Thread-1 will Tt all the odd numbers in between 1 and 100. Thread-2 will find the numbers divisible by 5 between 1 and 100. Thread-3 will check the number taken as input is prime or not.Exercise 4: In this program, you manipulate a Table, having an array of doubles, which is shared between 3 threads DepositThread and 3 other threads RemoveThread. - DepositThread increments (by 1) the values of the array.- RemoveThread decrements (by 1) the values of the array.- Every DepositThread and RemoveThread has a thread name.- Before starting the incrementing or decrementing task, every thread has to introduce itself by printing a sentence as follows: THREAD thread-name is incrementing/decrementing the array... Example: "THREAD DepositTh-1 is incrementing the array..." - The table is initially filled by zeros. So, logically, at the end of threads’ job, the table values must be all zeros again. - The main thread waits till all other threads finish execution, and then it prints the resulting array elements.- Class Table is given below: Table - tab[] : double + Table()+ incTab() : void+ decTab() : void+ displayTab() : void

Select 3 correct answer(s) In the Many-to-Many multithreading model, a process is always blocked whenever one of its threads is executing a blocking call A lightweight process (LWP) is a communication interface between different user threads of an application and is not used by user processes to map to kernel processes One advantage of multithreading is responsiveness, which means that one thread may respond instantly while other threads are blocked or busy doing calculations User threads must be mapped onto available kernel threads in order to be scheduled for execution by the CPU The Many-to-One multithreading model maps multiple user threads to many kernel threads A context switch between threads can be performed much faster than a context DELL O W
