Using the FIFO page removal algorithm, perform a page trace analysis indicating page faults with asterisks (). Then compute the failure and success ratios. b. Using the LRU page removal algorithm, perform 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
