The image can be scanned and saved in the computer as a graphic file. Obviously, you would need a device called a scanner (commonly, a flat-bed scanner taking A4 paper) which is linked by a USB cable to your computer. There are also printers that will also scan. There are also devices that can be drawn on using a special pen, that while drawing an image on the device, the result appears on your computer's monitor. You then save the completed image as a graphic file.

An Operating System.
A block special file that provides access to a device that transfers in groups of a fixed size. For example, a disk. A character special file that provides access to a device that transfers in increments of a single character; for example, a terminal.
In every Unix-like operating systems device files are used as interface to device drivers. Every device is represented in file system with a special file, these special files are called as Device Files. There are two standard types of device files: character special and block special. Character special files are used to interface character devices. Character devices transfer data in terms of character. Example of character devices mice, serial modems. Block special files are used to interface block devices. Block devices transfer data interms of blocks. Example of block devices hard disks, CD-ROMs.
Usually they are stored in /dev
It is a device file used for Parallel port. Consider the following command dir >prn (or) lpt1 dir >com1 dir >com2 that is the input is sent to the specified device file or device or a file.
In MS-DOS, several special "device files" were available to aid in performing certain tasks, such as clearing the screen or deleting extraneous output from a program. In order to maintain backwards-compatibility, all versions of Windows up to and including Windows Vista will refuse to allow you to create a file with these "reserved" device file names. The following file names are reserved:CONPRNAUXNULCOM1COM2COM3COM4COM5COM6COM7COM8COM9LPT1LPT2LPT3LPT4LPT5LPT6LPT7LPT8LPT9CON, incidentally, was a device file used to capture whatever was printed onscreen.

To open and view a CTG file on a Canon device, you need to transfer the file to the device using a USB cable or memory card. Once the file is on the device, navigate to the file using the device's file explorer or media player application to open and view it.
Is there a special device used for hood duct cleaning? Where can I buy such a thing?
The asterisk is a special character and cannot be used in the names of any kind of file.
Many computer commands move data from one file to another or from one storage device to another. This is referred to as moving the data from the source to the destination (or target). The term is also used as an adjective, as in destination file or destination device.So basically where every your moving your file or etc... too is the destination device.
Yes, although the data is still on the device even while a copy of it exists in memory. That's why many programs will ask about "writing over" a file, because the file is still there.
UNIX Q.How are devices represented in UNIX? A.Devices in UNIX are represented by files. These are special files located in the )dev directory. Hence in UNIX, every piece of hardware is a file. This device file allows us to access the hardware.UNIX represents all devices as files. These files are located in the directory /dev. That is why the devices and other files are accessed in a similar way.Devices file which is specified as 'block special file' with some similar characters of a disk file. A device which is specified as a 'character special file' with some characteristics that is similar to a keyboard.For instance, the following command; Less -f /dev/hda is not a file in the 'real' sense. When read, it is actually reading directly from the first physical hard disk of your machine.
