What else can I help you with?
Transfers data directly from the drive to memory without involving the CPU?
DMA
Generally which transfer mode is faster DMA or PIO?
DMA transfers data directly from the drive to memory without involving the CPU. PIO involves the CPU and is slower than DMA mode.
Which transfer mode can transmit data from a device to memory without involving the cpu?
DMA
Which bus transfers the memory address to the IO device or to the memory device?
DMA Direct Memory Access DMA transfers data directly from the drive to memory w/out involving the CPU.
What transfer mode can transmit data from a device to memory without involving the CPU?
DMA transfer mode
Why DMA is used?
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.
What transfers data directly from the drive to memory with out using the CPU?
DMA
Why is it important for the scheduler to distinguish IO-bound programs from CPU-bound programs?
Any CPU will have an I/O which en ply external devices data transfers. The CPU internally will process data. While both are data bus they are definitely not the same
Las caracteristicas y funciones del CPU?
The CPU processes data and is a key component in the function of the computer. It is a small square with fins or metal circles for transfers.
What is the two data transfer modes used in hard drives?
DMA (Direct Memory Access) or PIO (Programmed Input/Output) Transfer Modes. DMA transfers data to memory without use of the CPU. PIO involves CPU and is slower.ASCII & Binary
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.
Which motherboard feature controls the amount of data that a CPU transfers at one time?
the internal data path the address bus the clock speed the cache
