Virtually all computers provide a mechanism by which other modules (I/O, memory) may interrupt the normal sequencing of the processor. Most common classes of interrupts.
Program: Generated by some condition that occurs as a result of an instruction execution, such as arithmetic overflow, division by zero, attempt to execute an illegal machine instruction, and reference outside a user's allowed memory space.
Timer: Generated by a timer within the processor. This allows the operating system to perform certain functions on a regular basis.
I/O: Generated by an I/O controller, to signal normal completion of an operation or to signal a variety of error conditions.
Hardware failure: Generated by a failure, such as power failure or memory parity error.
Interrupts are provided primarily as a way to improve processor utilization.
Write an example for which the use of interrupt is enhances the utilization of processor. and please explain it

Method to calculate all primes in the range [2..n]
: One commonly used method to calculate all primes in the range [2..n] is to start with the number 2, mark it as prime, and mark all its multiples (excluding itself) as not prime. Then, we find the next smallest unmarked number, mark it as prime, and m..

Modify each sorting algorithm
: Modify each sorting algorithm so that it keeps track of the number of comparisons it performs and the number of exchanges (swaps) it performs during a single sorting operation. Keep track of these numbers using two long integer counters
