  1. 16 bit color
  2. image file size
  3. 24 bit color
  4. ASCII
  5. 32 bit integer
  1. a 64 thousand colours
  2. b 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.
  3. c 4 bytes with binary place values 2^0 to 2^31, maximum value (2^32)-1
  4. d 7 bit code representing (only) latin type alphabets and language symbols
  5. e 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 Multiple choice questions

  1. represents negative and positive numbers in the range -128 to +127
  2. some resolution data is lost, image quality affected
  3. resolution dependant (zooming will show pixels), large file size for high resolution / high colour depth, limited editing - pixel operations only
  4. graphic file size made smaller by using special algorithms to reduce amount of data needed for bitmap
  5. image stored as collection of shapes, each represented by set of numbers defining properties such as coordinates, line thickness, fill colour, layer level

5 True/False questions

  1. bit map advantagephotos, images that can't easily be represented as shapes


  2. Unicode16 bit code to represent characters from all the world's alphabets and symbols


  3. bit mapnumber of bits used to code a colour, aka colour depth


  4. 8 bit color64 thousand colours


  5. range7 bit code representing (only) latin type alphabets and language symbols
