Detailed explanation-1: -An “interrupt” is an event that stops the normal instruction cycle and causes the flow of execution to jump to a special section of code called an “interrupt handler”. A hardware interrupt is caused when a device sends a signal to the CPU.
Detailed explanation-2: -Timer interrupts allow you to perform a task at very specifically timed intervals regardless of what else is going on in your code.
Detailed explanation-3: -Timer Interrupts: Generated by a timer within the processor. This allows the operating system to perform certain functions on a regular basis. Hardware Failure Interrupts: Generated by a failure (e.g., power failure or memory parity error).
Detailed explanation-4: -Perhaps the most important interrupt for operating system design is the “timer interrupt", which is emitted at regular intervals by a timer chip. A software interrupt, also called a processor generated interrupt, is generated by the processor executing a specific instruction.
