slowest device for data transfer
I think it would be Cd's or Dvd's.
A direct data device is a device that can transfer data automatically from a document eg. a barcode reader reads a barcode
USB
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.
A wireless device, that lets you transfer, answer, or call for data from a device, like a Computer, or phone.
The transfer code is a temporary, one-time code used to establish a secure connection between two devices during data transfer. It ensures that files are sent only to the intended device and prevents unauthorized access. In many Android transfer tools, like MobiKin Transfer for Mobile, a transfer code may appear on the receiving device or computer. When you initiate the transfer from the sending device, you enter this code to verify and authorize the connection. This step encrypts the connection and confirms that both devices are ready for the data exchange. The code is typically numeric or alphanumeric and expires after a short time for security reasons. You don’t need to create it manually in most cases; the transfer tool generates it automatically during the setup process. Using a transfer code is particularly important when transferring sensitive data, like contacts, messages, or financial apps, because it ensures that the data goes directly to the chosen device without exposing it to the network or other devices nearby. In short, the transfer code acts as a secure handshake between devices, confirming the connection before files move, making the transfer safe, private, and reliable.
Transfer rate.
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
A data cable can be used to transfer information from a device to another device, such as a cell phone or computer.
A MTP (Media Transfer Protocol) device is a type of technology that allows for the transfer of media files, such as photos and videos, between a device (like a smartphone or camera) and a computer. It functions by establishing a connection between the device and the computer, enabling the seamless transfer of data. MTP devices use a standardized protocol to ensure compatibility and efficient communication during the data transfer process.
