Using the same data as question #$5$Given that main memory is composed of only four$-$page frames for public use, and that a seven$-$pageprogram $($with pages a$,$ b$,$ c$,$ d$,$ e$,$ f$,$ g$)$ requests pages in the following order:a$,$ b$,$ d$,$ b$,$ c$,$ a$,$ e$,$ f$,$ b$,$ e$,$ c$,$ f answer the following questions.Show all work and provide an explanation for your answers.b$.$ Using FIFO again, increase the size of memory so that it contains four page frames for public use. Usingthe same page requests as question #$5,$ do another page trace analysis and compute the failure and successratios.
