We have this common cliché saying that, 'garbage in, garbage out'. This is mostly related to computers and means that the input determines the output. The quiz below is on data output devices. All the best and enjoy. An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form. Output TypesSome types of output are text, graphics, tactile, audio, and video. Text consists of characters (letters, numbers, punctuation marks, or any other symbol requiring one byte of
computer storage space) that are used to create words, sentences, and paragraphs. Graphics are digital representations of non-text information such as drawings, charts, photographs, and animation (a series of still images in rapid sequence that gives the illusion of motion). Tactile output such as raised line drawings may be useful for some individuals who are blind. Audio is music, speech, or any other sound. Video consists of images played back at speeds to provide the appearance of full
motion. GraphicsA digital image is a numeric representation of an image stored on a computer. They don't have any physical size until they are displayed on a screen or printed on paper. Until that point, they are just a collection of numbers on the computer's hard drive that describe the individual elements of a picture and how they are arranged. Some computers come with built-in graphics capability. Others need a device, called a graphics card or graphics adapter board, that has to be added. Unless a computer has graphics capability built into the motherboard, that translation takes place on the graphics card. Depending on whether the image resolution is fixed, it may be of vector or raster type. Without qualifications, the term "digital image" usually refers to raster images also called bitmap images. Raster images that are composed of pixels and is suited for photo-realistic images. Vector images which are composed of lines and co-ordinates rather than dots and is more suited to line art, graphs or fonts. To make a 3-D image, the graphics card first creates a wire frame out of straight lines. Then, it rasterizes the image (fills in the remaining pixels). It also adds lighting, texture and color. Tactile OutputHaptic technology, or haptics, is a tactile feedback technology which takes advantage of the sense of touch by applying forces, vibrations, or motions to the user. Several printers and wax jet printers have the
capability of producing raised line drawings. There are also handheld devices that use an array of vibrating pins to present a tactile outline of the characters or text under the viewing window of the device. Audio OutputSpeech output systems can be used to read screen text to computer users. Special software programs called screen readers attempt to identify and interpret what is being displayed on the screen[9] and speech synthesizers convert data to vocalized sounds or
text. ExamplesThese examples of output devices also include input/output devices. Printers and visual displays are the most common type of output device for interfacing to people, but voice is becoming increasingly available.
