All of the following are examples of output devices except: aprinter bspeakers cscanner dmonitor

The answer is cscanner. A scanner is an input device, not an output device. It is used to input data into a computer system by scanning physical documents into digital format. On the other hand, a printer (option a), speakers (option b), and a monitor (option d) are all output devices. They output data from the computer system in the form of printed documents, sound, and visual display respectively.
