Consider devices you directly interact with versus those used for security.
Which of the following is a human-readable device?
Think about what you see and interact with.
True or False: DMA allows for direct data transfer between memory and I/O devices without CPU involvement.
Consider how heavy workloads are managed.
Consider a scenario where a computer must process a large file transfer using both programmed I/O and DMA. Analyze the differences in their efficiency and potential issues.
Evaluate the impact of CPU usage during data transfers.
Design a simple flowchart that illustrates the steps taken by the CPU to communicate with an I/O device, including I/O module functions.
Visual aids can often clarify processes effectively.
