5 Matching questions

  1. vector graphic
  2. data compression
  3. precision
  4. range
  5. image file size
  1. a image stored as collection of shapes, each represented by set of numbers defining properties such as coordinates, line thickness, fill colour, layer level
  2. b graphic file size made smaller by using special algorithms to reduce amount of data needed for bitmap
  3. c accuracy of a floating point value depends on number of bits for mantissa (significant digits)
  4. d bitmap file size depends on the resolution and the bit depth for pixel colour; (length in pixels) x (breadth in pixels) x (bit depth)
  5. e limit for smallest value (near zero) and largest value on number line depends on number of bits for exponent (moves the point)

5 Multiple choice questions

  1. 16 bit code to represent characters from all the world's alphabets and symbols
  2. limited types of image possible, drawings only
  3. resolution dependant (zooming will show pixels), large file size for high resolution / high colour depth, limited editing - pixel operations only
  4. photos, images that can't easily be represented as shapes
  5. Digital color model that uses eight bits each for the three additive colors (red, green, blue.) It can reproduce 256 shades of each primary color. Total 16 million shades. True colour.

5 True/False questions

  1. two's complement (8 bit)represents negative and positive numbers in the range -128 to +127

          

  2. bit mapbinary values corresponding to grid of pixels including colour code

          

  3. ASCII7 bit code representing (only) latin type alphabets and language symbols

          

  4. 8 bit color64 thousand colours

          

  5. 32 bit integerDigital color model that uses eight bits each for the three additive colors (red, green, blue.) It can reproduce 256 shades of each primary color. Total 16 million shades. True colour.
