Question 2.
What is the primary advantage of using DMA?
Show hintHide hint
Consider why multitasking is beneficial.
3Question 3.
What is the primary purpose of DMA?
- To increase CPU processing time
- To transfer data directly between devices and memory
- To reduce memory size
Show hintHide hint
Think about how devices share resources.
4Question 4.
True or False: In DMA operations, the CPU gets involved in transferring each byte of data.
- True
- False
Show hintHide hint
Reflect on the efficiency benefits of DMA.
Question 5.
Design a simple DMA controller logic for a system that can handle three different I/O devices needing access to memory. Describe how it would manage bus priority.
Show hintHide hint
Think about how shared resources can prioritize different needs.
Question 6.
Discuss the impact of data transfer rates on system performance if the DMA system supports connections at different speeds.
Show hintHide hint
Consider how different speeds can affect overall workflow efficiency.
