Why Direct memory access has priority over the CPU when both request a memory transfer?
we can transfer data direct to and from memory without the need of the CPU. The transfer of data between a fast storage device such as magnetic disk and memory is often limited by the speed of the CPU. Removing the CPU from the path and letting the peripheral device manager the memory buses directly would improve the speed of transfer. This transfer technique is called direct memory access(DMA). During DMA transfer, the CPU is idle and has no control of the memory buses. A DMA controller takes over the buses to manage the transfer directly between the I/O device and memory.

What is the process for accessing a Chase credit access line?
To access a Chase credit access line, you can log in to your Chase account online or through the mobile app. From there, you can navigate to the credit access line section and request a draw or transfer funds. Chase will review your request and if approved, the funds will be available for use.

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 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.
When you use hypertext transfer protocol to access content online what are you doing?
When you use Hypertext Transfer Protocol (HTTP) to access content online, you are initiating a request from your web browser to a web server. This request typically involves retrieving web pages, images, or other resources hosted on the server. The server processes the request and sends back the requested content, which your browser then displays. Essentially, HTTP facilitates the communication between your device and the server to enable the viewing of online content.
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)
