DMA - Direct Memory Access
The direct memory access or DMA mode of data transfer is the fastest amongst all the modes of data transfer.In this mode ,the device may transfer data directly to/from memory without any interference from the CPU.The device requests the CPU through a DMA controller to hold its data,address and control bus so that the device may transfer data directly to/from memory.
magic. and duct tape
it is a device to transfer the data directly between io device and memory without through the cpu so it performs a high-speed data transfer between memory and io device
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.
Yes, you can transfer the pictures from the memory card to a computer. Then transfer from the computer to the phone using the usb data cable that came with the phone. If you do not want to do that, you can take the memory card (not the sim card) out of the phone, find an adapter and connect it to your computer directly. Then transfer files.
You can transfer memory stick data to Gmail easily. It can be done via attaching the memory stick to computer. Then attaching files by browsing the memory stick.
In the 8085 microprocessor, direct data transfer between two memory locations is not possible. Data must first be loaded into a register from one memory location and then stored into another memory location. The 8085 can only transfer data between registers, memory, and I/O devices using specific instructions, but it does not support direct memory-to-memory transfers.
Data transfer instructions in the 8051 microcontroller are used to move data between registers, memory, and I/O ports. Key instructions include MOV (to transfer data between registers or memory), MOVC (to move data from code memory), and MOVX (to access external data memory). These instructions facilitate the manipulation and transportation of data within the microcontroller's architecture, enabling various operations in embedded applications.
There is a Device which has a PS2 memory card slot with a USB and it can be attached to PC to transfer your PS2 memory data to PC.
The transfer of pages of data between a computer's main memory and an auxiliary memory.
