Explanation:
Detailed explanation-1: -The direct memory access controller then takes control of the bus and begins transferring data between the device and memory. The CPU is only involved in setting up the DMA-controller and receiving an interrupt when the transfer is complete.
Detailed explanation-2: -To solve this problem, direct memory access (DMA) controllers were developed. It enables data transfer between two devices without involving the CPU. DMA is a feature in computers and devices with microprocessors that transfer data directly from main memory to an auxiliary device or vice versa.
Detailed explanation-3: -Bus-Master DMA. Third-party DMA. First-party DMA.
