Suppose we’re using a 32-bit system with 4 byte pointers. Suppose the system has 4KB pages with a single-level page table. How many entries are there in a page table? Show the steps.

A toddler’s parent/caregiver asks the nurse for suggestions on dealing with temper tantrums. The most appropriate recommendation is to: 

An infant usually begins to fear strangers around this age:

Consider the following page reference string: 7, 2, 3, 1, 2, 5, 3, 4, 6, 7, 7, 1, 0, 5, 4, 6, 2, 3, 0, 1.    Assuming demand paging with three frames, how many page faults would occur for the following replacement algorithms? • LRU replacement (4 points) • FIFO replacement (4 points) • Optimal replacement (4 points) Show the sequence to get full marks. Consider initially the cache to be empty. To answer, you may use the following technique: write the page fault on the side of the access that resulted in the page fault, and also note which page will be evicted, if any. Please do not forget to mention the total page fault for each case as well. 7(page fault, no eviction) , 2(page fault, no eviction), ……………………………..
