Given that main memory is composed of three page frames for public use and that a seven page program (with pages a, b, c, d, e, f, g) requests pages in the following order:
a, b, a c, d, a, e, f, g, c, b, g
a. Using the FIFO page removal algorithm, do pages 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 used. 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.
