Abstract
Using the link http://courses.cs.vt.edu/~csonline/OS/Lessons/VirtualMemory/index.html , to display the affectation, the scholar was directed to press the Start button in rate to initiate a sequence of operation in which the 8 processes that take turns referencing memory locations were accesses. Using the second simulation the student could actually see the effects on FIFO, LRU, LFU, SC and ergodic in the parameters of number of rapscallion faults, total number of page references and page fault rate %.
Unit 4 Project Virtual Memory
Part 1.
After pressing the Start button, a sequence of operation was initiated in which the 8 processes took turns referencing the memory locations. The boxes indeed turned dark blue, which indicated that a process was running.
When that box would flip-flop to light blue, it indicated that the process was ready to be run, but hadnt started as it was waiting for its turn. At first the page frames were exsanguine; which indicated that the frame was empty. After the start button was pressed and the simulation progress began, the running process chose a specific page.
If a page fault occurred, then the process would change pretext to red, and the requested page would be put into primary memory. The pertly pages in the page table were green. If a process wrote to a page, then the page would change from green to yellow. This indicated that the contents of the page had changed as well as the fact that it should be copied natural covering to disk before being replaced by another page, (Coutinho, 1996).
Part 2.
The second simulation figure illustrated the behavior of each of the 5 page...If you want to get a full essay, order it on our website: Ordercustompaper.com
