Given that accessing data from memory typically takes 10 cycles, and a page fault adds 50 cycles for retrieval, calculate the effective time spent retrieving data for 30 instructions where one results in a page fault.
💡 Hint: Remember to consider the proportion of hits to misses when calculating cycle time.
Question 2
