Input and Output Questions and Answers

Q: MICR character set consists of only 2 digits 0 and 1.

Correct answer: FalseThe E-13B character set used for MICR has fourteen characters: the ten digits 0 to 9 and four special symbols marking the transit, amount, on-us and dash fields on a cheque.Restricting it to two would make it useless for printing account and cheque numbers, which is its whole purpose. The characters have a deliberately distinctive shape, with thick and thin strokes, so that each produces a waveform the read head can distinguish unambiguously.

Q: Which of these is both an input and an output device ?

Correct answer: Touch screenA touch screen displays output and accepts input through the same surface, which is why it counts as both. A scanner and a light pen take input only, and a plotter produces output only.

Q: A light pen is classified as which type of device ?

Correct answer: Input deviceA light pen senses the position on a screen where it is held and reports it to the computer, so information travels inward. It is a pointing device, in the same family as the mouse, trackball and stylus.

Q: _________ is used to captures images in a digitized form that a computer can use.

Correct answer: Digital CameraA digital camera focuses an image onto a sensor - a CCD or CMOS array - which converts light into electrical charge and then into digital values, so the image arrives already in a form the computer can process.A film camera captures an image too, but on chemical emulsion, which must be developed and scanned before a computer can use it. A memory card stores what the camera produces, and an indicator LED on the case captures nothing.

Q: A __________ is a digital video camera that captures real-time video for transmission to others via a Web Server.

Correct answer: WebcamsA webcam is a digital video camera that produces a continuous stream rather than single frames, and the stream is sent over a network as it is captured - which is what "real-time" means here.The distinction from a digital camera is the continuity and the immediacy: a still camera stores what it captures for later transfer. It is an input device, converting a physical scene into data, and a storage chip merely holds what some other device produced.
