Answer 2

Direct memory access(DMA) involves designing of hardware to avoid the CPU perform the transfer of information between the device.

• It transfers data between the memory and peripheral devices of a computer without the intervention of the CPU.
• Its activity is controlled by the DMA controller. It can transfer data by using the system bus.
• Two other methods are also present for data transfer- programmed I/O and interrupt driven I/O.
