Question

Give 5 examples of external interrupts and 5 examples of internal interrupts.

Answer 1

Answer:

5 examples of external interrupt

• I/O device
• Power failure interrupt
• request transferring of data by I/O device
• time that elapsed by an event
• timeout interrupt

5 examples of internal interrupt

• stack overflow
• stack underflow
• divide by zero
• by invalid operation code
• violation of protection

Answer 2

external interrupts:

These are the interrupt initiated by the hardware of the system.

Examples: I/O devices: For an I/O transfer an interrupt can be initiated to take control of the CPU.

Example input from keyboard or mouse.

internal interrupts:

An interrupt that is caused by processing, for example, a request for input or output or an arithmetic overflow error.

Explanation:

An interrupt is a sign despatched to the processor that interrupts the cutting-edge process.

It can be generated via way of means of a hardware tool or a software program program.

A hardware interrupt is frequently created via way of means of an enter tool consisting of a mouse or keyboard.

An interrupt is despatched to the processor as an interrupt request, or IRQ. Interrupts have types: Hardware interrupt and Software interrupts.

In addition, it has a maskable interrupt and a non-maskable interrupt relying on how the interrupt request sign is received.
