10  10 chapter 5

*

11  an answer time  response time of an LCD is the moment in milliseconds (ms) that it takes to revolve a pixel top top or off.  LCD response times selection from 8 come 25 ms. The lower the number, the quicker the response time. LCD technology and top quality 11 chapter 5

*

12  Brightness of LCD is measure in nits.  A nit is a unit that visible light intensity. The higher the nits, the brighter the images. LCD modern technology and high quality 12 chapter 5

*

13  Pixel pitch  some times called dot pitch, is the distance in millimeters between pixels ~ above a display device.  typical pixel pitch on LCD need to be.28 mm or lower.  The lower the number, the trickster the image. 13 chapter 5 LCD modern technology and top quality

18   Is one output machine that to produce text and also graphics top top a physical tool such as file or transparency film.  numerous different printers exist through varying speed, capabilities and printing method. There space two type:  Nonimpact printer such as Ink-jet, Photo, Laser, Thermal, Mobile, Plotters and big format printers.  influence Printer such together dot-matrix printers and also line printers. 2. Printers 18 chapter 5

*

19  1. Nonimpact Printers  develops characters and graphics top top a piece of paper without striking.  some nonimpact printers spray ink, while rather use warm or push to develop images. Kind of printer: 19 chapter 5

*

20  Is a kind of nonimpact printer that creates characters and graphics through spraying small drops of liquid ink ~ above a piece of paper.  produce text and graphics in both black and white and color top top a variety of file types.  The resolution determines the top quality of one ink- jet printer. 20 thing 5 A. Ink-Jet Printers

*

21   Resolution is measured by the variety of dots per inch (dpi) a printer have the right to print.  most ink-jet deserve to print from 600 to 4800 dpi.  The rate of the is measure up by the variety of pages every minute (ppm) it have the right to print.  most ink-jet publish from 3 to 26 ppm. Ink-Jet Printers 21 chapter 5
