1. What is an interrupt in the context of computer organization?

• A hardware failure

• A signal generated by the CPU to initiate I/O operations

• A mechanism to temporarily stop the execution of a program and transfer control to another part of the system

• A type of memory error

2. Which hardware component is responsible for generating interrupts in response to external events?

• Memory

• CPU

• Interrupt Controller

• I/O Devices

3. What is the purpose of the interrupt vector in the context of interrupts?

• To store the address of the next instruction to be executed after the interrupt is handled

• To store the address of the interrupt service routine (ISR)

• To manage memory hierarchy during interrupts

• To control the execution of the program

4. Which type of interrupt cannot be ignored by the CPU and requires immediate attention?

• Maskable interrupt

• Non-maskable interrupt

• Software interrupt

• External Interrupt

5. What is the role of the interrupt request (IRQ) line in the context of interrupt hardware?

• To initiate I/O operations

• To indicate the priority of interrupts

• To carry the interrupt signal from devices to the interrupt controller

• To store the interrupt vector

6. In a priority-based interrupt system, how are multiple interrupt requests resolved?

• By the order in which they are received

• By the priority level assigned to each interrupt

• By the CPU speed

• By the interrupt vector value

7. What is the purpose of the interrupt acknowledge signal in the interrupt handling process?

• To acknowledge the receipt of an interrupt request

• To initiate I/O operations

• To indicate the priority of interrupts

• To carry the interrupt signal from devices to the interrupt controller

8. Which register in the CPU is used to store the address of the next instruction to be executed after the interrupt is handled?

• Program Counter (PC)

• Memory Address Register (MAR)

• Stack Pointer (SP)

• Instruction Register (IR)

9. What is the purpose of the interrupt service routine (ISR) in the interrupt handling process?

• To acknowledge the receipt of an interrupt request

• To store the address of the next instruction to be executed

• To perform the specific actions required to handle the interrupt

• To initiate I/O operations

10. In a vectored interrupt system, how is the type of interrupt identified by the CPU?

• By polling each interrupt line

• By the interrupt request (IRQ) line

• By the interrupt vector value

• By the interrupt acknowledge signal
