CGS 2060 Output

4K Ultra TV

-Use LED tech -have four times the picture resolution of Full HD 1080p.

liquid crystal display (LCD)

-most common type of display for computer monitors -layers of filter

3D Printing

Cross sections of the object are first created and then successive layers of material, usually plastic, are sprayed through a nozzle to recreate the object.

Refresh rate

How fast each pixel is updated -higher the refresh rate the smoother the video -plays best at even multiples with the frame rate

light emitting diode (LED)

Liquid Crystal Displays with a screen of white LEDs to backlight the display. -convert electricity to light

Resolution

Number of pixels in a display

digital-to-analog converters

Speakers then change the analog electrical impulses to sound by physically pushing air.

Aspect Ratio

The width of the screen compared to the height

Optical Media

These discs store data using reflective material placed in the coating of a plastic disc. A laser "reads" this reflected data.

Peripheral

a device that connects to a computer -enhance capabilities of digital devices -connected via wires or radiowaves

Dot Matrix Printer

a type of impact printer -recreates output by physically striking an ink coated ribbon with a metal rod.

Output

anything created with a computer, meaningful information or non-discern able data

Plasma Display Panels

create images with pixels made of red, green, and blue cells. -filled with ionized gas called plasma. -send electricity to each cell to vary the brightness of the cell.

Projectors(halide lamps)

create output using a very bright lamp. The brightness of the light emitted from the projector is rated in lumens.

Monitors

electronic, fixed-screen device that visually displays computer output. -tablets -smartphones -computers

CRT (Cathode Ray Tube)

glass picture tube to display video output.

Inkjet

most common printers -print by spraying droplets of ink onto the substrate, usually paper. -Canon, Epson, HP, and Lexmark, Brother

Laser Printers

popular printers for use in business offices because they use relatively inexpensive toner rather than liquid ink. -faster than inkjet printers when printing multiple copies -spinning cylindrical drums, and a laser to transfer images onto paper.

Printers

recreate a computer image onto paper or other substrate -resolution is described as dots per inch. -speed = pages per minute

Sampling Rate

the accuracy of a digital recording. Sound is an analog signal aka digitalized

Ergonomics

the art of designing products that present information in the most useful way. -improve mental concentration and physical capability by providing only the information that is needed at the time. -modern cars, aircraft, ships, and many other devices.

Bit depth

the number of bits of data describing each pixel in a display

Organic Light Emitting Diode displays(OLED)

use red, green, and blue LEDs to create each pixel. -more expensive than LCD

Thermal Printing

used most commonly for creating receipts.

Plotters

used to print large graphic images such as designs of buildings, machinery, and ships. - recreate images by mechanically moving a pen over a large sheet of paper.

Digital Light Processing (DLP)

uses thousands of tiny mirrors that are controlled by a processor to create output.
