Quizplus · Accepted Answer

A non-maskable interrupt (NMI) is a type of interrupt that cannot be disabled or ignored by the processor. NMIs are generally used to indicate critical events or errors, such as hardware malfunctions or system crashes. When an NMI occurs, the processor stops executing its current task and jumps to a specific location in memory to handle the interrupt. This often results in a proprietary crash screen being displayed to the user, indicating that a critical error has occurred. Therefore, choice B, "By displaying a proprietary crash screen," is the best answer. None of the other options accurately describe the manifestation of an NMI.
