What is interrupt and its types?
Hardware interrupts can be classified into two types they are.
Maskable Interrupt: The hardware interrupts which can be delayed when a much highest priority interrupt has occurred to the processor.
Non Maskable Interrupt: The hardware which cannot be delayed and should process by the processor immediately..
What is an interrupt in OS?
In digital computers, an interrupt is a response by the processor to an event that needs attention from the software. An interrupt condition alerts the processor and serves as a request for the processor to interrupt the currently executing code when permitted, so that the event can be processed in a timely manner.
What is the purpose of interrupt?
Interrupts are signals sent to the CPU by external devices, normally I/O devices. They tell the CPU to stop its current activities and execute the appropriate part of the operating system.
What is another word for interrupt?
In this page you can discover 74 synonyms, antonyms, idiomatic expressions, and related words for interrupt, like: hinder, disrupt, intervene, interfere, continue, discontinue, obtrude, put in, butt in, obstruct and edge in.
What happens when interrupt occurs?
When an interrupt occurs, it causes the CPU to stop executing the current program. The control then passes to a special piece of code called an Interrupt Handler or Interrupt Service Routine. The interrupt handler will process the interrupt and resume the interrupted program.
How many types of interrupts are there?
TYPE 1 interrupt represents single-step execution during the debugging of a program. TYPE 2 interrupt represents non-maskable NMI interrupt. TYPE 3 interrupt represents break-point interrupt. TYPE 4 interrupt represents overflow interrupt.
What is interrupt example?
The definition of an interrupt is a computer signal that tells the computer to stop running the current program so that a new one can be started or a circuit that carries such a signal. An example of an interrupt is a signal to stop Microsoft Word so that a PowerPoint presentation can gear up.
What is a sentence for interrupt?
Examples of interrupt in a Sentence Verb It’s not polite to interrupt. His dinner was interrupted by a phone call. We interrupt this program to bring you a special announcement.

How does interrupt work?
An interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. 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.
How are interrupts handled?
Most modern general purpose microprocessors handle the interrupts the same way. When a hardware interrupt occurs the CPU stops executing the instructions that it was executing and jumps to a location in memory that either contains the interrupt handling code or an instruction branching to the interrupt handling code.
What are the classes of interrupt?
There are six classes of interrupts possible:External.Machine check.I/O.Program.Restart.Supervisor call (SVC).
