Question 1.
What is programmed I/O?
Show hintHide hint
Think about how the CPU interacts with devices.
Question 2.
Define polling in the context of I/O.
Show hintHide hint
Consider how the CPU ensures devices are ready for communication.
3Question 3.
What does programmed I/O require the CPU to do?
- Send interrupts
- Check status bits
- Wait indefinitely
Show hintHide hint
Consider how the CPU controls communication with I/O devices.
4Question 4.
True or False: In programmed I/O, the I/O module can directly interrupt the CPU.
- True
- False
Show hintHide hint
Think about how the CPU and I/O device communicate.
Question 5.
Design a simple interaction between a CPU and an I/O device using programmed I/O. Include steps for issuing commands, checking status, and reading/writing data.
Show hintHide hint
Break down each part of the interaction into clear, logical steps.
Question 6.
Discuss how using programmed I/O can lead to inefficiencies in CPU performance and suggest possible alternatives.
Show hintHide hint
Think about how interaction dynamics between devices and the CPU can be improved.
