Question

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

Answer 1

What IS the question? If you were trying to "cut and paste" it did not work and you will need to type the rest of this out.

Answer 2

4. 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 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 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
