What is a trap instruction?
A trap instruction is a software interrupt. It's generated by an error or by a user program when it needs the operating system to perform an operation (a system call).
What is the purpose of interrupts in Operating System?
Answer: An interrupt is a hardware-generated change-of-flow within the system. An interrupt handler is summoned to deal with the cause of the interrupt; control is then returned to the interrupted context and instruction. A trap is a software-generated interrupt. An interrupt can be used to signal the completion of an I/O to obviate the need for device polling. A trap can be used to call operating system routines or to catch arithmetic errors.Type your answer here...
