Older technology than DLP projectors, and has a high intensity beam of light. v It has a microprocessor as a central processing unit, memory, storage area, input unit and output unit. Integrated device:a touch sensitive device, resembling a, Integrated devices: sends resistance to the device in response to actions, Force-Feedback Joysticks, wheels, gamepads, and motionsensing, T/F: Line printers is a high-speed, non-impact printer that prints an entire line at a time, T/F: OCR is a technology that reads hand-drawn marks such as small circles or rectangles, False, OCR is a technology that reads printed or handwrittern caracters, T/F: The Dot Pitch of a LCD monitor measures the sensitivity of the monitor to high pitch sound outputs. Hope you will li. 3D printers scan solid objects and produce a three-dimensional image. Rather than using liquid ink, they used dry powder ink to produce text and images. No need for humans (can loose people their jobs). Media/Code capturing devices: a device that uses a light source to read characters. Found inside – Page 128Input 2 Figure 6-5 . - Data buffering . ... Data is collected from , or sent to , the input / output devices in words or in fixed groups of characters . The other type of projector is LCD, this is a older type of projector and uses a high intensity beam of light which passes through an LCD display and then onto the screen. A print head which consists of nozzles which spray droplets of ink on to the paper to form characters. Powerful white light beam is generated from a bulb or LED inside the projector, The beam is sent to a group of chromatic-coated mirrors, these reflect light back at different wavelengths, When the white light hits the mirrors, the reflected lights has wavelengths that correspond to red, green, and blue light components, These three beams then pass through three LCD screens; these screens show the image to be projected as millions of pixels in a grey scale, When the colored beams pass through the LCD screen, the colored version of the grey image emerges, These images are then combined using a special prism to produce a full color image – this final image consists of millions of colors (each shade of grey in the original image produces a different shade in each of the color images), The image passes through the projector lens onto the screen, They reach maximum brightness much faster, They give a whiter light making the image more vivid, The brighter light improves colour definition, The displays can be much thinner and lighter in weight. LCD monitors need a back light in order to function, usually they use CCFT however the newer ones started using LED lights to support them . Users can interact with touch screens by. Inkjet printers are the most commonly used type of printer, and range from small inexpensive consumer models to expensive professional machines. If the output is from a computer, the digital signals will then first be converted into analogue voltages using DAC. 3,742 output and input device stock photos, vectors, and illustrations are available royalty-free.
