. Given that main memory is composed of three page frames for public use and that a program requests pages in the following order:
d c b a d c e d c b a e
a. Using the FIFO page removal algorithm, do a page trace analysis indicating page faults with asterisks (*). Then compute the failure and success ratios.
b. Increase the size of memory so it contains four page frames for public use. Using the same page requests as above and FIFO, do another page trace analysis and compute the failure and success ratios.
c. Did the result correspond with your intuition? Explain.
7. Given that main memory is composed of three page frames for public use and that a program requests pages in the following order:
a b a c a b d b a c d
a. Using the FIFO page removal algorithm, do a page trace analysis indicating page faults with asterisks (*). Then compute the failure and success ratios.
b. Using the LRU page removal algorithm do a page trace analysis and compute the failure and success ratios.
c. Which is better? Why do you think it is better? Can you make general statements from this example? Why or why not?
d. Let us define “most-recently-used” (MRU) as a page removal algorithm that removes from memory the most recently used page. Do a page trace analysis using the same page requests as before and compute the failure and success ratios.
e. Which of the three page removal algorithms is best, and why do you think so?
I do not know
