- You could implement an application as either a uni-threaded process or a multi-threaded process or as multiple 1) Discuss the pros and cons of each of the three approaches listed above 2) In case you choose the multi-threaded process approach, how does it matter whether the threads are user-level threads or kernel-level threads? Discuss the pros/cons of both 3) If you were using kernel level threads and your machine is a uniprocessor, is there any benefit in running the application as a multi-threaded process versus; a uni-threaded process?arrow_forwardWhy do you think all threads that are active within a Java virtual machine share the same method area?arrow_forwardIs there ever a time when using user-level threads rather than kernel-level threads is the best option?arrow_forward
- Do you believe every virtual machine thread uses the same JVM method space?arrow_forwardDo user-level threads have any benefits over kernel-level threads? How different are threads created by the user and those created by the kernel?

- Can you please help me with this code because I am struggling on how to do this, This has to be in C code. question that I need help with: Write a multithreaded program that calculates various statistical values for a list of numbers. This program will be passed a series of numbers on the command line and will then create three separate worker threads. One thread will determine the average of the numbers, the second will determine the maximum value, and the third will determine the minimum value. For example, suppose your program is passed the integers 90 81 78 95 79 72 85 The program will report The average value is 82 The minimum value is 72 The maximum value is 95 The variables representing the average, minimum, and maximum values will be stored globally. The worker threads will set these values, and the parent thread will output the values once the workers have exited. (We could obviously expand this program by creating additional threads that determine other statistical values,…arrow_forwardIs the usage of user-level threads superior than kernel-level threads? What is the difference between user-level threads and kernel-level threads? Is there ever a period when one kind is superior than another?arrow_forwardIs there a reason why all of the threads running in a virtual machine share the method area?arrow_forward
