Clues

  • (or bit depth) The number of bits used for each pixel. The more bits the more colours that can be represented. (6, 5)
  • 1024 bytes (8)
  • 1024 kilobytes (8)
  • 1024 megabytes (8)
  • A register in the CPU that keeps the address of the next instruction (7, 7)
  • Register in CPU that stores data currently being used by the CPU (11)
  • The base-16 number system (11)
  • The characters available to a computer (9, 3)
  • The number of pixels per unit (ppi - pixesl per inch - is popular) (10)
  • The number of times the sound is sampled per second, measured in Hz. Affects the quality of sound. High sample rate = improved quality but creates larger file. (6, 4)
