Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What does an interrupt indicate?

💡 Hint: Think about events external to the CPU that may need immediate processing.

Question 2

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does the Program Counter (PC) do?

  • Stores the current instruction controls execution flow.
  • Tracks the address of the next instruction to execute.
  • Controls input/output devices.

💡 Hint: Recall which component directs the flow of instruction execution.

Question 2

True or False: The Instruction Cycle Code (ICC) helps determine if the CPU is executing the instruction, fetching it, or servicing an interrupt.

  • True
  • False

💡 Hint: Consider what keeps the CPU organized during instruction processing.

Question 1

Design a flowchart that depicts the fetch phase, including the handling of interrupts and the role of the program counter.

💡 Hint: Remember to represent decision points clearly to show interrupt checks.

Question 2

Discuss the implications of not saving the PC value during an interrupt. What potential issues could arise?

💡 Hint: Think about how processes rely on correct sequential order for execution.
