Question 1.
What does DMA stand for?
Show hintHide hint
Think of the purpose of DMA in data transfer.
Question 2.
What is one key benefit of using DMA?
Show hintHide hint
Consider how CPU workloads are managed.
3Question 3.
What method does DMA use for data transfer?
- Through CPU processing
- Direct transfer without CPU intervention
- Using interrupts
Show hintHide hint
Remember the role of DMA in reducing CPU tasks.
4Question 4.
True or False: Interrupt-driven I/O allows CPU multitasking during data transfers.
- True
- False
Show hintHide hint
Consider how the CPU handles interrupts.
Question 5.
Describe the implications of using DMA in data-intensive applications like video editing software. How does it affect overall performance?
Show hintHide hint
Consider how DMA's operation contrasts with traditional data handling.
Question 6.
Evaluate a scenario where interrupt-driven I/O could be problematic in a high-speed network environment. Illustrate how DMA could resolve these issues.
Show hintHide hint
Think about data flow and speed in network communications.
