What else can I help you with?
What resource is allows a hardware device to directly access RAM?
direct memory access (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.
Storage device that connect directly to camera without computer?
memory card, like SD or Memory Stick
What is a portion of memory that is allocated to a device?
A portion of memory allocated to a device is commonly referred to as a memory-mapped I/O space or device memory. This area of memory is reserved for the device to store data related to its operations, such as buffers for input/output processing. It allows the CPU to communicate with the device by reading from and writing to specific memory addresses associated with that device. This allocation is essential for efficient data transfer and control between the CPU and peripheral devices.
What is the purpose of command device himem.sys in the config.sys file?
To activate himem.sys which frees up more conventional memory and allows for DOS to be loaded into the HMA (high memory area) It manages memory as a device
What is the physical address stored in a special memory location in the device called?
The physical address stored in a special memory location in a device is commonly referred to as the "base address" or "device address." This address serves as a reference point for accessing the device's memory-mapped I/O registers or for direct memory access (DMA) operations. It allows the CPU to communicate with the device efficiently by mapping specific memory locations to the device's functions.
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 the advantage of Direct Memory Access?
DMA allows a peripheral device to read from/write to memory without going through the CPU. DMA allows for faster processing since the processor can be working on something else while the peripheral can be populating memory.
Why DMA controller data transfer is faster?
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.
Does DFU mode wipe your memory if not will it wipe your memory if done incorrectly?
DFU (Device Firmware Update) mode itself does not automatically wipe your device's memory; it allows you to install firmware or restore your device without loading the operating system. However, if you proceed with a restore or update in DFU mode, it will erase all data on the device. Performing DFU mode incorrectly, such as disconnecting the device during the process, may lead to issues, but it typically won't erase your memory unless you initiate a restore.
How can I determine the memory size of a device by calculating it?
To determine the memory size of a device, you can calculate it by multiplying the number of memory cells by the size of each memory cell. This will give you the total memory size of the device.
Is a random access memory a input or output device or both?
Random Access Memory (RAM) is the volatile memory that is both an input and an output. You input data into the memory and can output the result on the monitor or print it out on paper, etc.
