Question 1.
What comprises CPU time?
Show hintHide hint
Think about what occurs when the CPU is processing data.
Question 2.
What does a page fault indicate?
Show hintHide hint
Consider what happens to a program when it accesses memory.
3Question 3.
What factors determine CPU time?
- Execution cycles only
- Memory stall cycles only
- Both execution and stall cycles
Show hintHide hint
Consider what activities contribute to CPU time.
4Question 4.
True or False: A low miss rate can lead to increased effective memory access time.
- True
- False
Show hintHide hint
Think about the relationship between access frequency and retrieval delays.
Question 5.
You have a system with a miss rate of 5% and a hit time of 80 ns. If the miss penalty is 200 ns, calculate the effective memory access time.
Show hintHide hint
Use the effective memory access formula discussed.
Question 6.
Explain in detail how using FIFO for page replacement could lead to suboptimal performance in certain access patterns.
Show hintHide hint
Think about how a continuous loop in access could hinder memory efficiency.
