$1-$ Imagine a demand$-$paged computer system with a current fixed degree of

multi$-$programming set at four. Recent measurements were taken to assess

CPU and paging disk utilization, resulting in the following scenarios:

a$.$ CPU utilization is $25\%,$ while disk utilization is $90\%.$

b$.$ CPU utilization is $70\%,$ with disk utilization at $10\%.$

c$.$ CPU utilization stands at $20\%,$ while disk utilization is at $5\%.$

For each case:

$$ Interpret the observed CPU and disk utilizations. What might be occurring

in each scenario?

$$ Can the degree of multi$-$programming be increased to improve CPU

utilization?

$$ Evaluate the effectiveness of paging in these situations. Is it contributing

positively?

$2-$ Explain the hardware functionalities necessary to facilitate demand paging.
