- 83. A state is safe, if : a. the system does not crash due to deadlock occurrence b. the system can allocate resources to each process in some order and still avoid a deadlock c. the state keeps the system protected and safe d. all of the mentionedIS A SECTION OF CODE WITHIN A PROCESS THAT REQUIRES ACCESS TO SHARED RESOURCES AND THAT MAY NO BE EXECUTED WHILE ANOTHER PROCESS IS IN A CORRESPONDING SECTION OF CODE. Select one: a.MUTUAL EXCLUSION b.CRITICAL SECTION c.COMPETING PROCESSES d.RACE CONDITIONWrite a single program to perform the following tasks:a) Main process should create a child process. Both parent and child processes will create one thread (e.g. parent process thread A, child process thread B).b) Compare the ids of parent and child, parent process and thread A, parent process and thread B, child process and thread A, child process and thread B. Display appropriate messages as per your comparison results.c) Parent process will take a number from user as input and will pass on this number to thread A while creating it. Before doing anything else, thread A will print the cube of that number.d) Parent process will perform some tasks and then wait for the termination of child process. Similarly, thread B will wait for the termination of thread A before starting execution. Each process and thread will display an appropriate message before its termination.e) Parent process will send your Name and Roll number to the child process and you will save them in two different…
- Context: One operating system (Linux) treats processes and threads in the same way, allowing a task to be more akin to a process or a thread (as described in our text) depending on flags passed to the system call that creates it. Another operating system (Windows) treat processes and threads quite differently. The Process Control Block contains pointers to the separate threads belonging to the process.Question: Contrast these two approaches for modeling processes and threads within the kernel. What differences do the two approaches make? What are some consequences? (Operating system and concept )What is the maximum number of processes that may be executed in parallel at the same time?a set of processes is deadlock if
- Process States: Select all of the following statements that are true. Hardware interruptions are the only causes for process state changes. The process state ZOMBIE is assigned to a process that is terminated and removed from memory, but still has an entry in the management structures. A process in the state WAITING/BLOCKING can directly change to the state RUNNING when a respective signal arrives. The process state "SWAPPED OUT AND BLOCKED" is assigned to a process that is currently blocked and not in main memory. A child process whose parent has terminated is referred to as an orphan. A parent process may terminate the execution of its children processes.Why is it necessary to add an exception in a process's scheduling?Which strategy of allowing processes that are logically runnable to be temporarily suspended is called?
- 102. The two ways of aborting processes and eliminating deadlocks are : a. Abort all deadlocked processes b. Abort all processes c. Abort one process at a time until the deadlock cycle is eliminated d. All of the mentionedWrite a single program to perform the following tasks: Main process should create a child process. Both parent and child processes will create one thread (e.g. parent process à thread A, child process à thread B). Compare the ids of parent and child, parent process and thread A, parent process and thread B, child process and thread A, child process and thread B. Display appropriate messages as per your comparison results. Parent process will take a number from user as input and will pass on this number to thread A while creating it. Before doing anything else, thread A will print the cube of that number. Parent process will perform some tasks and then wait for the termination of child process. Similarly, thread B will wait for the termination of thread A before starting execution. Each process and thread will display an appropriate message before its termination. Parent process will send your Name and…If a process exits and there are still threads of that process running, will they continue to run?
