Clues

  • A circuit made by combining a sequence of logic gates. (5, 7)
  • A CPU with multiple processors (a dual-core has two, a quad-core has four). (4, 8, 4)
  • A method for mathematicaly expressing a logic circuit. (7, 7)
  • A section of the hard disk used as if it were RAM to supplement the amount of main memory available to the computer. Used when there is not enough main memory to run the programs required. (7, 6)
  • A store for data in a computer the cannot be overwritten. Data in ROM is always available and is not lost when the computer is turned off. (4, 4, 6, 3)
  • Non-volatile storage used to store programs and files that need to be kept even when the power is not on. (9, 7)
  • Secondary storage device using magnetised platters to store data and files. (8, 4, 4)
  • Solid-state memory used as low cost secondary storage in portable devices and as removable memory. (5, 6)
  • The central printed circuit board (PCB) that holds the crucial components of the system. (11)
  • The process of fetching the instructions from memory, decoding them and then executing them so that the CPU performs continuously. (5, 7, 5)
