Explanation:
Detailed explanation-1: -When an interrupt occurs, the hardware saves pertinent information about the program that was interrupted and, if possible, disables the processor for further interrupts of the same type. The hardware then routes control to the appropriate interrupt handler routine.
Detailed explanation-2: -Timer Interrupts: Generated by a timer within the processor. This allows the operating system to perform certain functions on a regular basis.
Detailed explanation-3: -Whenever an interrupt occurs, the controller completes the execution of the current instruction and starts the execution of an Interrupt Service Routine (ISR) or Interrupt Handler. ISR tells the processor or controller what to do when the interrupt occurs.
