Question 1.
What is a control signal?
Show hintHide hint
Think about communication between the CPU and I/O devices.
Question 2.
What does the interrupt signal indicate?
Show hintHide hint
Consider what happens when a device has finished its task.
3Question 3.
What is the purpose of the interrupt request signal?
- To signal that I/O data is ready
- To indicate a device is not busy
- To alert the CPU of an I/O event
Show hintHide hint
Think about what happens when a device finishes its job.
4Question 4.
True or False: In interrupt-driven I/O, the CPU must constantly check if the device is ready.
- True
- False
Show hintHide hint
Think about how the CPU handles tasks while waiting.
Question 5.
Analyze a scenario where an interrupt-driven I/O system has to handle multiple different I/O devices. Discuss how control signals manage these interactions effectively.
Show hintHide hint
Focus on how the CPU would manage multiple interrupts.
Question 6.
Design a mini-computer architecture that effectively utilizes interrupt-driven I/O. List the control signals required.
Show hintHide hint
Think about the roles each signal plays in the context.
