The correct answer is: B. Hardware interrupt<\/strong><\/p>\n A hardware interrupt is a signal sent to the CPU by a hardware device, indicating that the device needs attention. The CPU will then stop what it is doing and handle the interrupt. Hardware interrupts are typically used for devices that need to be accessed quickly, such as the keyboard and mouse.<\/p>\n A software interrupt is a signal sent to the CPU by a software program, indicating that the program needs to be interrupted. The CPU will then stop what it is doing and handle the interrupt. Software interrupts are typically used for tasks such as input\/output and error handling.<\/p>\n An internal interrupt is a signal sent to the CPU by the CPU itself, indicating that an internal error has occurred. The CPU will then stop what it is doing and handle the interrupt. Internal interrupts are typically used for errors such as divide by zero and memory access errors.<\/p>\n An external interrupt is a signal sent to the CPU by a device outside of the CPU, such as a timer or a network card. The CPU will then stop what it is doing and handle the interrupt. External interrupts are typically used for devices that need to be accessed quickly, such as the keyboard and mouse.<\/p>\n Fast interrupt exception is a type of interrupt that is handled by the CPU very quickly. This is because fast interrupt exceptions are typically used for devices that need to be accessed quickly, such as the keyboard and mouse. Hardware interrupts are the only type of interrupt that can generate fast interrupt exceptions.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Software interrupt” option2=”Hardware interrupt” option3=”Internal interrupt” option4=”External interrupt” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[686],"tags":[],"class_list":["post-19578","post","type-post","status-publish","format-standard","hentry","category-embedded-systems","no-featured-image-padding"],"yoast_head":"\n
