Explanation:
Detailed explanation-1: -Stands for “Interrupt Service Routine.” An ISR (also called an interrupt handler) is a software process invoked by an interrupt request from a hardware device. It handles the request and sends it to the CPU, interrupting the active process. When the ISR is complete, the process is resumed.
Detailed explanation-2: -To identify which device issued the interrupt, the CPU runs a program called an interrupt handler. The interrupt handler generates queries to each device interface.
Detailed explanation-3: -IRQ (Interrupt Request) An (or IRQ) is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler, to run instead.
