What is the purpose of the instruction cycle?
Think about the steps involved in processing an instruction.
Define the term 'interrupt'.
Consider who or what generates interrupts.
What happens when an interrupt is received by the CPU?
Consider the importance of responding to signals from I/O devices.
True or False: Context switching is only necessary when the CPU has completed all instructions.
Reflect on what occurs when an interrupt is triggered.
Explain how a CPU with interrupt handling improves performance over one that only uses polling for I/O operations.
Consider the difference between waiting and responding immediately.
Design a simple instruction cycle diagram reflecting checks for interrupts and context switching.
Include distinct paths for when interrupts are present versus absent.
