View Answer, 11. a) 16 a) 16 For LRU page replacement algorithm with 5 frames, the number of page faults is? A system that is thrashing can be perceived as either a very slow system or one that has come to a halt. A directory of Objective Type Questions covering all the Computer Science subjects. a) it defines a new locality For 3 page frames, the following is the reference string : Which of the following is not a communication command? d) none of the mentioned 1 2 3 4 2 1 5 6 2 1 2 3 7 6 3 2 1 2 3 6 View Answer, 6. View Answer, 8. c) 14 View Answer, 10. View Answer. In thrashing, state CPU is so much busy in swapping that it cannot respond to user program as much as it required. it is spending more time paging than executing, it is spending less time paging than executing, Which command will display the kernel version of linux operating system, Which command can be used to check the name of a computer system in linux. c) 8 d) none of the mentioned A process is thrashing if it is spending more time paging than executing it is spending less time paging than executing page fault occurs swapping can not take place. c) it has no memory allocated to it d) {1, 2, 3, 4, 5} In the working set model, for: View Answer, 9. Attempt a small test to analyze your preparation level. b) it is in the same locality from where it was called A process is thrashing if ____________ Thrashing occurs when a process is spending more time in paging or swapping activities rather than its execution. a) a set of pages that are actively used together b) keeps constant 1. c) it will cause memory problems b) {2, 1, 6, 7, 3} c) it will cause memory problems 1 2 3 4 2 1 5 6 2 1 2 3 7 6 3 2 1 2 3 6 I'm assuming that "thrashing" here refers to a situation where the active memory set of all processes is too big to fit into memory. This causes the performance of the computer to degrade or collapse. d) 11 b) must What is a locality? d) none of the mentioned In computer science, thrashing occurs when a computer's virtual memory resources are overused, leading to a constant state of paging and page faults, inhibiting most application -level processing.
