the interrupt which can be ignored by the processor ,while performing its operations are called maskable interrupts. generally maskable interrupts are the interrupts that comes from the pheripheral devices.
where as the non maskable interrupts are the interrupts which cannot be ignored. generally these type of interrupts are specified to be software interrupts.
the examples of maskable are: mouseclick,memoryread etc
the examples of non_maskable are:powerfailure,software corruptedetc

What is the difference between polling and vectored interrupt system with example?
i need compare between vectored interrupt system and polling
Difference between internal and external interrupt?
internal interrupt is synchronous with the program while external interrupts are asynchronous.
What is the difference between polling and vector interrupt service routine?
polling interrupt is alternative to the vector interrupt , it requires that the interrupt handler poll or send a signal to each device in turn in order to find out which one is sent the interrupt request.....
Difference between interrupt and subroutine in computer?
interrupt is a signal caused by I/O devices where as subroutine is a part of the program which is excuted rapidly
What is the difference between polling and vector interrupt system?
In a computer, a vectored interrupt is an I/O interrupt that tells the part of the computer that handles I/O interrupts at the hardware level that a request for attention from an I/O device has been received and also identifies the device that sent the request. A vectored interrupt is an alternative to a polled interrupt , which requires that the interrupt handler poll or send a signal to each device in turn in order to find out which one sent the interrupt request.
What is the exact difference between interrupt handling and exception handling?

What is the difference between software and hardware interrupt?
The difference is that a hardware interrupt is a signal relayed to a system's CPU directly because of some piece of hardware, such as a keyboard or mouse. A software interrupt is a signal sent to indicate that something within a piece of software requires attention.
What interrupt is best to avoid because it is used as a connection between two interrupt controller chips?
In an IBM PC or compatible computer, IRQ2 should not be used because it is internally cascaded from the second 8259 Programmable Interrupt Controller, so as to provide IRQ8 through IRQ15.
How did political teachings interrupt the school day?
