Quizplus · Accepted Answer

BIOS manages IRQ (Interrupt Request) lines that are used by a device to interrupt the CPU and ask for data to be processed. DMA (Direct Memory Access) lines are used by devices to access system memory directly, ACK (Acknowledgment) lines are used to acknowledge receipt of data or signals, and ARQ (Automatic Repeat Request) lines are not related to system interrupts or device communication.
