DMA
DMA Direct Memory Access DMA transfers data directly from the drive to memory w/out involving the CPU.
DMA transfers data directly from the drive to memory without involving the CPU. PIO involves the CPU and is slower than DMA mode.
DMA
DMA, or Direct Memory Access, is used to enable peripherals to transfer data directly to and from system memory without involving the CPU. This reduces the processing load on the CPU, allowing it to perform other tasks while data transfers occur in the background. DMA is particularly beneficial for high-speed data transfers, such as in audio and video processing, where efficiency and speed are crucial. By streamlining data transfer, DMA enhances overall system performance and responsiveness.
DMA
Implicit memory is unconscious memory, involving skills and routines, while explicit memory is conscious memory, involving facts and events. Implicit learning is learning without awareness of what is being learned, while explicit learning is intentional and conscious learning.

Direct Memory Access (DMA) has priority over the CPU when both request a memory transfer because DMA can access memory independently of the CPU, allowing for simultaneous data transfers. This reduces the burden on the CPU and improves overall system performance. Additionally, DMA transfers are typically faster and more efficient than CPU transfers, making them a preferred choice for handling memory transfers.
To retrieve photos from a camera without a memory card, you can connect the camera to a computer using a USB cable and transfer the photos directly from the camera's internal memory.
