Answer: 0
The given statement is FALSE (represented as 0).
Explanation:
- Programmed I/O: The CPU continuously monitors (polls) the status of the I/O device in a loop until the device is ready for data transfer. This busy-waiting wastes a significant number of CPU clock cycles, making the overall system extremely inefficient.
- Interrupt-driven I/O: The CPU does not waste time polling. Instead, it performs other useful tasks and is only interrupted by the I/O device when the device is ready for the transfer.
While both methods require CPU intervention to move data between the I/O device and memory (unlike DMA, which bypasses the CPU), programmed I/O is highly inefficient due to polling overhead and does not result in faster data transfer rates compared to interrupt-driven I/O. Therefore, the statement is false.
