A hardware interrupt is not really part of CPU multitasking, but may drive it.
Hardware interrupts are issued by hardware devices like disk, network cards, keyboards, clocks, etc. Each device or set of devices will have its own IRQ (Interrupt ReQuest) line. Based on the IRQ the CPU will dispatch the request to the appropriate hardware driver. (Hardware drivers are usually subroutines within the kernel rather than a separate process.)
The driver which handles the interrupt is run on the CPU. The CPU is interrupted from what it was doing t...

Interrupt - Wikipedia
Interrupt signals may be issued in response to hardware or software events. These are classified as hardware interrupts or software interrupts, respectively. For any particular processor, the number of interrupt types is limited by the architecture. Hardware interrupts A hardware interrupt is a condition related … See more
In digital computers, an interrupt (sometimes referred to as a trap) is a request for the processor to interrupt currently executing code (when permitted), so that the event can be processed in a timely … See more
Hardware interrupts were introduced as an optimization, eliminating unproductive waiting time in polling loops, waiting for external events. The first system to use this approach was the See more
Each interrupt signal input is designed to be triggered by either a logic signal level or a particular signal edge (level transition). Level-sensitive inputs continuously … See more
The processor samples the interrupt trigger signals or interrupt register during each instruction cycle, and will process the highest priority … See more
Interrupts may be fully handled in hardware by the CPU, or may be handled by both the CPU and another component such as a programmable interrupt controller See more
