Consider a system that uses pure demand paging:
a. When a process first start execution, how would you characterize the page fault rate? b. Once the working set for a process is loaded into memory, how would you characterize the page fault rate? c. Assume a process changes its locality and the size of the new working set is too large to be stored into available free memory. What are some options system designers could choose from to handle this situation?
When a page fault occurs, the process requesting the page must block while waiting for the page to be brought from disk into physical memory. Assume there exists a process with five user-level threads where the mapping of user threads to kernel threads is many to one. If one user thread incurs a page fault while accessing its stack, would the other user user threads belonging to the same process also be affected by the page fault (i.e., would they also have to wait for the faulting page to be brought into memory?) Explain.
What (if any) relation holds between the following pairs of sets of algorithms (a) Priority and SJF (b) Multilevel feedback queues and FCFS
Simulation of Elevator and Shortest Seek Time First
Given that main memory is consisted of three page frames for public use and that seven-page program (with pages a, b, c, d, e, f, g) requests pages in the following order: a, b, a, c, d, a, e, f, g, c, b, g.
Remembering that there's a trade-off between memory use. Then give an example where doing so will cause throughput to suffer.
The software house has been contacted by a Governmental Nuclear Reactor Agency that wants to change the current Operating System of their plant.
What is race condition in this protocol?debitcard machine determine current value of card in dollars which is stored in value x.
Explain the difference between internal fragmentation and external fragmentation. Which one occurs in paging system? Which one occurs in system using pure segmentation?
Analysis and implementation of algorithms for memory allocation in operating system, Explain First- t and best- t methods are used in memory allocation in operating systems.
What does fragmented mean in reference to hard drives, and what, if anything, should be done to prevent it. Describe the general path data takes in an application from user input to the computer hardware.
Implement the parser in a separate file. Implement the main parser function in a separate file main.c
Explain the concepts of consumable and reusable resources
Computer has 16 pages of virtual address space but only three physical pages frames. Initially physical memory is empty. Program references virtual pages in order 1,2,3,4,5,3,4,1,6,7,8,7,8,9,7,8,9,5,4,5,4,2 Which references a page fault with LRU ..
