Answer:
Interrupt (INT) helps operating system to stop work on one process and start work on other process using interrupt signals.
Explanation:
Purpose of interrupts:
• Interrupts are useful when an I/O device needs to be serviced only occasionally at low data transfer rate.
• For example, when a peripheral requires the attention of the processor to perform an I/ O operation.
A trap:
• also known as an exception or a fault, is typically a type of synchronous interrupt caused by an exceptional condition
• is a software-generated interrupt.
• For example it's caused by division by zero or invalid memory access.
Can traps be generated intentionally by a user program? Yes.
If so, for what purpose?
• the usual way to invoke a kernel routine (a system call) because those run with a higher priority than user code.
• Handling is synchronous, so the user code is suspended and continues afterwards.
• In a sense they are active - most of the time, the code expects the trap.
