Question:
Which type of I/O does NOT use interrupts?
Which type of I/O does NOT use interrupts?
Show Hint
Programmed I/O uses busy-wait loops instead of interrupts — less efficient than interrupt-driven I/O.
Updated On: Jun 10, 2025
- Interrupt driven I/O
- Programmed I/O
- Direct Memory Access
- Daisy chaining
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Programmed I/O involves CPU polling the device status continuously, rather than being interrupted. This wastes CPU cycles but avoids using interrupts.
