Final answer:
A 'hardware interrupt' occurs when a user presses a hardware button on a device, signaling the processor to handle the event immediately.
Step-by-step explanation:
When a user presses a hardware button on a device, a hardware interrupt event occurs. An interrupt is a signal sent to the processor by hardware or software indicating an event that needs immediate attention.
In the case of a hardware button press, the device's operating system will typically be notified by the interrupt request so that it can proceed with the appropriate action, such as turning on the screen, adjusting the volume, or taking a picture with a camera. This is an essential part of how computers and other electronic devices manage inputs and tasks concurrently.
When a user presses a hardware button on a device, a button press event occurs. This event is triggered by the physical interaction with the button, and it can be detected by the device's software. The software can then respond to the button press event by performing a specific action or executing a certain function.
