But LL, LST, and EDD are aperiodic scheduling. Capacity of the disk = 16 surfaces X 128 tracks X 256 sectors X 512 bytes = 256 Mbytes. 2 (A) P – 3 Q – 2 R – 1 Rate monotonic scheduling is used in real-time operating systems with a static-priority scheduling class. Writing code in comment? Answer (A) First, is the inheritance lazy (only when essential) or immediate (boost priority before there is a conflict). (B) P – 1 Q – 2 R – 3 Free operating system basics MCQs, microcomputer processor, searching web, spreadsheet program cells, measuring and improving drive performance, operating system basics test prep for online computer science engineering. Rate monotonic analysis is used in conjunction with those systems to provide scheduling guarantees for a particular application. Practice "Operating Systems" quiz questions and answers, operating system basics Multiple Choice Questions (MCQ) for online computer science degree. The static priorities are assigned on the basis of the cycle duration of the job: the shorter the cycle duration is, the higher is the job’s priority. Explanation: The RMS os rate monotonic scheduling is periodic scheduling algorithm but EDD, LL, and LST are aperiodic scheduling algorithm. (D) 55, Answer (B) Swap space is typically used to store process data. So the number of bits required to access a sector is 19. Rate monotonic scheduling is used in real-time operating systems with a static-priority scheduling class. the system may or may not be schedulable. 0.77976 Some gardens are books. Statements: All chairs are sofas. Which of the following is an independent scheduling? The child process gets an exact copy of parent process and virtual address of ‘a’ doesn’t change in child process. Rate monotonic analysis is comparatively simple because it makes simplifying assumptions. The physical addresses of ‘a’ in parent and child must be different.

This set of MCQ questions on uni-processor scheduling in the operating system includes the collections of the top 30 multiple-choice questions on different types of scheduling methods.It also includes MCQ questions on long-term scheduling, medium-term scheduling, and short-term scheduling. The other 30.7% of the CPU can be dedicated to lower-priority non real-time tasks. Please see GATE Corner for all previous year paper/solutions/explanations, syllabus, important dates, notes, etc. Operating System Objective type Questions and Answers. Get hold of all the important CS Theory concepts for SDE interviews with the CS Theory Course at a student-friendly price and become industry ready. At time 30, P3 is the shortest remaining time process. "In rate monotonic scheduling", operating system basics Multiple Choice Questions (MCQs) with choices longer duration job has higher priority, shorter duration job has higher priority, priority does not depend upon duration of jobs, and average duration job has higher priority for online computer science schools. Which of the following do the sporadic events are connected? So P2 continues for 10 more time units. {\displaystyle 3\,} Experience. a) yes b) no c) maybe d) none of the mentioned View Answer Explanation: The rate monotonic scheduling is a periodic scheduler algorithm which follows a preemptive algorithm. P2 runs for 5 time units. {\displaystyle {\frac {1}{8}}+{\frac {2}{5}}+{\frac {2}{10}}=0.725} Practice test for UGC NET Computer Science Paper. Hard real time operating system has ___ jitter than a soft real time operating system. Match entries in Group 1 to entries in Group 2.

RM scheduling of Task set in table 1. The deadline-monotonic scheduling algorithm is also optimal with equal periods and deadlines, in fact in this case the algorithms are identical; in addition, deadline monotonic scheduling is optimal when deadlines are less than periods. , Operating System Numerical Questions and Answers, If block size is large then seek time is less (fewer blocks to seek) and d. Since kernel level threads are managed by kernel, blocking one thread doesn’t cause all related threads to block. Which of the following can be applied to periodic scheduling? At time 40, P2 runs as it is the only process. EDF and LL have dynamic priorities. LL is also preemptive scheduling but it is aperiodic scheduling algorithm. Which of the following are used to execute at regular intervals and check for ready sporadic tasks? All nets are gardens. acknowledge that you have read and understood our, GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Program for Banker’s Algorithm | Set 1 (Safety Algorithm), Operating Systems | Input Output Systems | Question 5, Commonly Asked Operating Systems Interview Questions | Set 1, Page Replacement Algorithms in Operating Systems, Practice questions on Height balanced/AVL Tree, Write Interview
