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.

What are the two methods that a hard drive uses to transfer data between itself and memory?
DMA (direct memory access) transfer mode or PIO (programmed input/output) transfer mode
Does Keflavik Airport Lounge accept Priority Pass for access"?
Yes, Keflavik Airport Lounge accepts Priority Pass for access.
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
What phrase will be used to indicate disapproval of a CMA or runway access request by the Control Tower?
The phrase commonly used by the Control Tower to indicate disapproval of a CMA or runway access request is "Request Denied." This succinctly communicates that the request cannot be accommodated, typically due to safety or operational concerns. Additional guidance may be provided if necessary, but the primary phrase remains clear and direct.
What is the difference between backing store swapping and roll out roll in swapping?
nBacking Store - fast disk large enough to accommodate copies of all memory images for all users; must provide direct access to these memory images. nRoll out, roll in - swapping variant used for priority based scheduling algorithms; lower priority process is swapped out, so higher priority process can be loaded and executed. nMajor part of swap time is transfer time; total transfer time is directly proportional to the amount of memory swapped. Modified versions of swapping are found on many systems, i.e. UNIX and Microsoft Windows
What is modes of transfer in Computer architecture?
Data transfer between the central computer and input and output devices may be handled in a variety of modes The techniques of data transfer are: Programmed I/O Interrupt driven Direct Memory Access (DMA)
What form of access control is based on access control lists that define which users can access objects?
the passive entity that is the target of an access request. the active entity that initiates an access request.
