A Non-Maskable Interrupt (NMI) is a hardware interrupt that cannot be ignored by the processor, ensuring critical tasks are addressed immediately regardless of the current state of the system. NMIs are typically used for high-priority tasks such as hardware failure alerts or emergency shutdown procedures, providing a mechanism for the system to respond promptly to urgent conditions.

Non-Maskable Interrupt

A hardware interrupt is a signal sent to the processor by external hardware devices, prompting it to temporarily halt its current execution to address the interrupt. This mechanism allows real-time processing and prioritization of critical tasks, ensuring efficient and responsive system performance.

A processor, also known as a central processing unit (CPU), is the primary component of a computer that performs most of the processing inside a computer. It interprets and executes instructions from hardware and software, acting as the 'brain' of the computer to carry out tasks and operations efficiently.

Emergency shutdown procedures are critical safety protocols designed to quickly and safely halt operations in hazardous situations, minimizing risk to personnel, equipment, and the environment. These procedures are meticulously planned and regularly practiced to ensure swift and effective response during actual emergencies.
