- A thread with priority 30 is currently active. What if it consumed the whole of its time quantum? b) Is there an I/O bottleneck?A thread with priority 30 is active. What if it exhausted its whole time quantum? b) Is it I/O-restricted?At the moment, work is being done by a thread with the priority 30. If (a) it used up all of its time quantum, what would be its re-assigned priority? If b is correct, then I/O has been blocked.
- A thread with the priority of 30 is presently running. What would its new priority be if it: (a) used up all of its time quantum? (b) I/O was obstructed?Problem 0. Write a version of hello.c that creates and reaps (joins) n threads, each of which prints "Hello, world" and its thread id, where n is a command-line argument, and the thread function is passed a pointer to its thread ID as its argument.A thread with priority 30 is currently executing. What would its re-assigned priority be if: (a) it used up all of its time quantum? (b) I/O was blocked?
- A thread is running at priority 30. What is its re-assigned priority if: (a) it used its entire time quantum? (b) it blocked for I/O?ed 00 The OS can perform context switching while using one of the following scheduling algorithms O a FIFO Oh SIF c. Any preemptive algorithm Od. Answer does not exist Clear my choiceSuresh and Ramesh started creating an application where it requires to do some mathematical operations.They are going to deploy it in a server. They wanted to do simultaneous execution of multiple parts ofprograms to utilize CPU time. They decided to create 2 separate threads for operations: num**2 andsqrt(num) with sleep of 100ms each.Write a program containing two threads and each thread should have a sleep of 100 ms. One thread is forcalculating the square of the elements in the array and other is for square roots.Trace the output in the threads only. Use Exception handling to handle and trace the interruptions if they occur.Input: An array. Can use static data. Preferably try to use run() and start().Output:"Thread 1"+ square(num)"Thread 2"+ square root(num)likewise to distinguish the thread status
- The following page table is for a system with 16-bit virtual and physical addresses and with 4,096-byte pages. The reference bit is set to 1 when the page has been referenced. Periodically, a thread zeroes out all values of the reference bit. A dash for a page frame indicates the page is not in memory. The page-replacement algorithm is localized LRU, and all numbers are provided in decimal.
