Question 1

What does polling mean in I/O operations?

The CPU waits for an interrupt.
The CPU continuously checks device status.
I/O devices communicate directly with memory.

💡 Hint: Consider how the CPU interacts with devices during polling.

Question 2

True or False: In interrupt-driven I/O, the CPU must constantly check the status of devices.

True
False

💡 Hint: Think about how devices signal the CPU.
