Define the cancellation of threads and the thread that will be the target of the cancellation.

Describe the use of thread priorities and scheduling algorithms in managing thread execution.

THREAD -"C LANGUAGE" ONLY   Write a program that uses 5 threads. Initialize a shared variable with a value of 0. Each thread must add its Thread ID (tid) to the shared variable. Once a thread has done the addition, print the ID of the thread. It is important to make use of mutexes so that only one thread is incrementing the shared variable at a time. Output the value of the shared variable once all threads have finished incrementing it.

In this question, assume a standard system with isolation and memory protection. Further assume that the thread abstraction is implemented by the operating system. That is, thread_create() is a system call. 1. What do you think are the differences between the implementation of thread_create(func) and the implementation of fork()? (here, func is the address of the function that the thread should begin at). 2. What do you think are the key differences between the OS's "process" data structure and whatever data structure it uses to implement a thread?

Modify the above thread program so that you implement the interface Runnable. Make themain thread waiting till all other threads finish execution.

Describe the concept of a thread pool and its role in managing threads in a multithreaded application.

Determine the distinction between user-level threads and kernel-level threads.

Fill in the blanks:5. The ( 6 ) is used to implement mutual exclusion where it can be decremented by aprocess and incremented by another, but the value must either be 0 or 1.6. If deadlock prevention approach is used to deal with deadlocks in a system, the ( 7 )condition can be prevented using the direct method.7. Two threads may share the memory space, but they cannot share the same ( 8 )8. Consider round-robin (RR) scheduling algorithm is implemented with 2 seconds timeslice and it is now selecting a new process; if we have 3 blocked processes (A, B, and C),and A has been waiting the longest, then A would need to wait a period of ( 9 ) secondsto be selected.9. In real-time systems, if a task appears at random times, then it is considered ( 10 ).

Write java code to create a thread by (extending), theprogram create 3 thread that displaying “fatmah” and thenumber of thread that is running.Rewrite the above program by implementing the RunnableInterface

Describe the concept of thread pools and their significance in managing threads efficiently in concurrent applications.
