A real machine is a physical device that performs mechanical tasks in the physical world. It operates based on principles of physics and mechanics to convert inputs into outputs. Examples include cars, washing machines, and computers.
If it pertains to electrical controls on a machine then the safety device is called an emergency stop button.
A mechanical device such as a gear, pulley, lever, or motor can transmit and modify motion or force. These devices are commonly used in machinery and mechanical systems to convert and control mechanical energy.
The page of text is first scanned and then an Optical Character Recognition (OCR) software program is used to convert the scanned text file into a machine-encoded text file that the user can edit and make changes to. So the device is a scanner, usually a flat-bed scanner, or a hand-held scanner, or a printer that has an inbuilt scanner.
