What are two methods that a hard drive uses to transfer data between itself and memory?

dma - direct memory access. (cpu not involved and can process other tasks) pio - programmed input output. (cpu controlled process which blocks other tasks from running.)


What is a numeric page?

The transfer of pages of data between a computer's main memory and an auxiliary memory.


Which of the data transfer is not possible in 8085 microprocessor?

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.


What do you mean direct memory acess?

direct data transfer between input and output device on the memory is called as direct memory acess


What is the purpose of an SD to CF adapter and how does it facilitate the transfer of data between different types of memory cards?

An SD to CF adapter allows for compatibility between SD and CF memory cards. It facilitates data transfer by physically adapting the size and shape of the SD card to fit into a CF card slot, enabling the transfer of data between different types of memory cards.


Block diagram of 8257 dma controller?

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


What is data transfer instructions in 8051?

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.


How can I use an SD to CF converter to transfer data between different types of memory cards?

To transfer data between different types of memory cards using an SD to CF converter, simply insert the SD card into the converter and then insert the converter into the CF card slot on your device. The data can then be transferred between the two memory cards as needed.


What are the advantages to switching to DDR3 memory?

DDR3 memory has a high bandwidth interface and can transfer data at between two and eight the speed of other memory and has the capacity of up to eight megabytes.


How do you copy between N64 memory cards?

To copy between N64 memory cards, you'll need an N64 memory card adapter or a compatible device like the Nintendo 64 Transfer Pak. First, insert both memory cards into the adapter or the Transfer Pak, then use the appropriate software on your N64 game that supports memory management, such as "Pokémon Stadium." Follow the on-screen prompts to select the data you want to transfer and complete the copying process. Make sure to save any changes before removing the cards.


Why Direct memory access has priority over the CPU when both request a memory transfer?

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.


Are there memory cards available for the xbox 360 besides the internal memory?

Yes, there are several different memory cards available for purchase for the Xbox 360. In this way you can transfer savegames and other information between systems.
