Clues

  • AVERAGE - magnetic tape can hold its data for up to thirty years in the correct environment (4, 4, 10)
  • Designed to carry out a specific role (9, 8)
  • Directs operations in a computer's processor - lets components know how to respond to instructions (7, 7, 4)
  • GOOD - offers up to several terabytes per device (5, 5, 8)
  • HIGH - no moving parts so little risk of damage. Can be written to over and over. Decreases over time, however (5, 5, 10)
  • Monitor, speaker, printer (6, 6, 8)
  • Mouse, keyboard, touchscreen (5, 6, 8)
  • Part of CPU that carries out arithmetic operations on instruction operands (10, 5, 4)
  • Separate data and instruction buses - transfers can be performed simultaneously on both buses (7, 12)
  • Speed at which a processor executes instructions, measured in Hertz (5, 5, 5, 4)
