Question 1.
What is the primary function of DMA?
Show hintHide hint
Think about how data is transferred in a computer.
Question 2.
Name one mode of DMA transfer.
Show hintHide hint
Both terms were discussed in our previous lessons.
3Question 3.
What is the advantage of DMA over interrupt-driven I/O?
- A: CPU can continue executing tasks
- B: Faster than CPU
- C: Does not require bus control
- D: None of the above
Show hintHide hint
Think about how DMA affects the CPU during data transfers.
4Question 4.
True or False: In DMA, the CPU must pause its operations to allow data transfers.
- True
- False
Show hintHide hint
Recall our discussion on the efficiencies of DMA.
Question 5.
Given the data transfer rates of Burst and Cycle Stealing modes, analyze which would be more efficient for high-volume data applications.
Show hintHide hint
Consider system demands and CPU workload.
Question 6.
You are tasked with designing a system where both DMA and interrupt-driven I/O are used. Explain the scenarios where each would be optimal.
Show hintHide hint
Think about minimizing delays and maximizing throughput.
