The explanation for the given question is described in the explanation section below.

Explanation:

An interrupt seems to be a mechanism whereby modules like I/O or storage will interrupt regular CPU processing. It may also be through pressing on a cursor, pushing a key, writing a document, etc.

There will be, essentially, three categories of interrupts such as:

Software Interrupt. Internal Interrupt. External Interrupt.

The control circulates then shifts to a special application segment called Interrupt Provider or Try to disrupt management routine. The Interrupt handler will identify the interruption and restart the program. Statement swapping is the core feature of Interrupt Handling. This would be the method of processing and retrieving the CPU state.

If the management process has been finished, the operation of the program proceeds.
