    • Input and output devices.
      • Input devices
        • Any device that gives information to the computer.
        • Motion sencer
      • Output devices
        • Any device that does something based on what the programme is doing.
        • Console controllers as they vibrate
    • Sound
      • Analogue sound is sound that is pure. Analogue sound can not be stored.
        • To convert analogue sound to digital sound, it has to be recorded.
          • This is done using sampling. Snippets of the sound are recorded at tiny intervals.
      • Digital sound is recorded sound that is impure.

      • Binary is how computers represent data internally.
        • Computers can only store 1s and 0s. This is all that they can use. To show this as letters, numbers or symbotls they use ASCII
