Types of Interrupts

Hardware interrupts are classified into two types
Maskable Interrupt − The hardware interrupts that can be delayed when a highest priority interrupt has occurred.
Non Maskable Interrupt − The hardware interrupts that cannot be delayed and immediately be serviced by the processor.
Software interrupts
A software interrupt occurs when an application software terminates or when it requests the operating system for some service.
Normal Interrupts − The interrupts that are caused by the software instructions are called Normal Interrupts.
Exception − Exception is an unplanned interruption while executing a program. For example − if we get a value that is divided by zero is called an exception
