Question

PLEASE HELP WITH PARTS A AND B FOR THIS QUESTIONS! If possible also provide explanations/instructions on how to solve it!! 

Consider the following sequence of virtual memory references (in decimal) generated by
a single program in a pure paging system:
100, 110, 1400, 1700, 703, 3090, 1850, 2405, 4304, 4580, 3640
a) Derive the corresponding reference string of pages (i.e. the pages the virtual
addresses are located on) assuming a page size of 1024 bytes. Assume that page
numbering starts at page 0. (In other words, what page numbers are referenced.
Convert address to a page number).
b) For the page sequence derived in part (a), determine the number of page faults for
each of the following page replacement strategies, assuming that 2 page frames are
available to the program. (Assume no TLB)
1) LRU
2) FIFO
3) OPT (Optimal)
