9.2.1. Hardware Interrupts

Try these first

1. 1.

   What is a hardware interrupt?

   Hint

   Think about what happens when a device wants the CPU's help.

2. 2.

   Give an example of a hardware interrupt.

   Hint

   Consider common devices that send data.

3. 3.

   What is a hardware interrupt?

   • A signal from the CPU
   • A signal from an external device
   • A software signal

   Hint

   Remember how devices communicate with the CPU.

4. 4.

   True or False: A timer interrupt can pause the CPU to handle time-sensitive tasks.

   • True
   • False

   Hint

   Think about when a timer is used in real life.

5. 5.

   Describe how hardware interrupts improve the performance of a real-time operating system. Provide an example demonstrating this.

   Hint

   Think about the implications of delays in systems where timing is essential.

6. 6.

   Discuss the consequences of handling a hardware interrupt incorrectly. What would be the effect on system stability?

   Hint

   Reflect on the role of interrupts in maintaining system integrity and performance.
