When does interrupt concur? Suppose that a disk drive has the cylinder numbered from 0 to 199. The head is currently at cylinder number 53. The queue for services of cylinders is as 99, 183, 37, 122, 14, 124, 65 and 67. What is the total head movement in each of following disk algorithm to satisfy t

An interrupt is a signal to the CPU from hardware or software indicating that an event needs immediate attention. When an interrupt occurs, the CPU suspends the currently executing process, saves its state, and transfers control to an Interrupt Service Routine (ISR). Interrupts occur in the follo...
