Using the second base make-believe the student could actually see the effects on FIFO, LRU, LFU, SC and ergodic in the parameters of number of rapscallion faults, congeries number of page references and page fault rate %. Unit 4 Project Virtual Memory Part 1. after pressing the Start butto n, 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 restore to be run, but hadnt firsted 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, therefore the process would swap pretext to red, and the requested page would be put into primar! y memory. The pertly pages in the page remit 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 forwards 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 point a full essay, order it on our website: BestEssayCheap.com
