  7. (6.06) __________ rate is the number of times per second that a CRT monitor redraws the images on the screen and is measured in hertz (Hz).
  8. (6.07) An 8-bit video card (also called 8-bit color) uses 8 bits to store information about each pixel and can display 64 / 128 different colors.
  9. (6.08) Manufacturers indicate the amount of __________ memory in megabytes (MB).
  10. (6.12) Gas palsma displays offer larger / smaller screen sizes and higher / lower display quality than flat panel displays, but are much more expensive.

  15. (6.16) The speed of an inkjet printer is measured by the number of pages per second (pps) / pages per minute (ppm) it can print.
  16. (6.18) Many inexpensive __________ printers use ink-jet technology.
  17. (6.20) Basic __________ printers are inexpensive, but the print quality is low and the images tend to fade over time.
