COMPUTER FUNDAMENTALS

Detailed explanation-1: -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.

Detailed explanation-2: -An interrupt is a signal emitted by hardware or software when a process or an event needs immediate attention. It alerts the processor to a high priority process requiring interruption of the current working process.

Detailed explanation-3: -The hardware mechanism that enables a device to notify the CPU is called an interrupt. The CPU hardware has a wire called the interrupt request line that the CPU sense after executing every instruction.

Detailed explanation-4: -An interrupt request (IRQ) is a signal sent to a computer’s processor to momentarily stop (interrupt) its operations. The signal is usually sent by a hardware device to interrupt the processor so the device gets some time to run its own operation.

Detailed explanation-5: -An interrupt is a signal from a device attached to a computer or from a program within the computer that requires the operating system to stop and figure out what to do next. Whenever an interrupt occurs, it causes the CPU to stop executing the current program.
