Question:
Which of the following interfaces perform the transfer of data between the memory and the I/O peripheral without involving the CPU?
Which of the following interfaces perform the transfer of data between the memory and the I/O peripheral without involving the CPU?
Show Hint
DMA is the standard interface for CPU-independent transfers; verify context if DDA is expected as the answer.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Note: The widely accepted answer is (3) DMA (Direct Memory Access), as it is designed specifically to handle data transfer between memory and peripherals without CPU intervention.
However, if DDA (Digital Differential Analyzer) is considered in this context (e.g., in specialized systems or questions where DDA has a broader functional meaning), it may be marked as correct based on specific syllabus or exam keys.

- Given Data:
- Two processors: \( M_1 \) and \( M_2 \)
- Four processes: \( P_1, P_2, P_3, P_4 \)
- CPU bursts: \( P_1 = 20 \), \( P_2 = 16 \), \( P_3 = 25 \), \( P_4 = 10 \)
- Priority order for \( M_1 \): \( P_1 > P_3 > P_2 > P_4 \)
- Priority order for \( M_2 \): \( P_2 > P_3 > P_4 > P_1 \)
- Scheduling: Non-preemptive priority scheduling
Step 1: Assigning Processes to Processors
At \( t = 0 \), both processors are free. The highest-priority process for each processor is scheduled:
- \( M_1 \) gets \( P_1 \) (highest priority on \( M_1 \), burst = 20 ms).
- \( M_2 \) gets \( P_2 \) (highest priority on \( M_2 \), burst = 16 ms).
Step 2: Scheduling Remaining Processes
- \( P_2 \) finishes at \( t = 16 \), so \( M_2 \) picks the next highest-priority process, \( P_3 \) (burst = 25 ms).
- \( P_1 \) finishes at \( t = 20 \), so \( M_1 \) picks \( P_4 \) (burst = 10 ms).
- \( P_4 \) finishes at \( t = 30 \), and \( P_3 \) finishes at \( t = 41 \).
Step 3: Calculate Waiting Times
- \( P_1 \) starts at 0, so waiting time = \( 0 \) ms.
- \( P_2 \) starts at 0, so waiting time = \( 0 \) ms.
- \( P_3 \) starts at 16, so waiting time = \( 16 \) ms.
- \( P_4 \) starts at 20, so waiting time = \( 20 \) ms.
Step 4: Compute Average Waiting Time
\[ \text{Average waiting time} = \frac{(0 + 0 + 16 + 20)}{4} = \frac{36}{4} = 9 \text{ ms}. \]
Final Answer: The average waiting time of the processes is \( 9 \) milliseconds.- GATE CS - 2025
