9.1. Introduction to Interrupts

Try these first

1. 1.

   What is an interrupt?

   Hint

   Think about its role in the CPU's operation.

2. 2.

   Give one example of an interrupt.

   Hint

   Consider devices that require immediate processing.

3. 3.

   What is the main purpose of interrupts?

   • To perform constant checks
   • To halt tasks and process urgent events
   • To extend CPU life

   Hint

   Think about the efficiency they provide.

4. 4.

   True or False: Interrupts are only generated by hardware events.

   • True
   • False

   Hint

   Consider sources of hardware and software events.

5. 5.

   Consider a system that processes inputs from a keyboard, mouse, and a temperature sensor. Discuss how interrupts help manage these inputs efficiently.

   Hint

   Think about the importance of timely processing for user interaction and data accuracy.

6. 6.

   Explain the trade-offs of using interrupts in a system designed for real-time applications versus a traditional polling method.

   Hint

   Consider the context of system requirements and resources available.
