- - - - The number of samples taken every second
      - This is measured in Hertz (Hz)- 6 samples - 6 Hz
  - - - The more accurately we record the wave height
      - The more frequently we sample the sound
  - - - E.g 10 x 5 takes less space to store than 5+5+5+5+5+5+5+5+5+5
- - - - 1 bit=2 colours
      - 2 bits=4 colours
      - 3 bits=8 colours
      - 4 bits=16 colours
  - - - 0 or a 1 + 1 bit (Binary Digit)
      - 8 bits = 1 byte
      - 1000 bytes= 1 kilobyte
      - 1000 kilobytes= 1 megabyte
      - 1000 megabytes= 1 gigabyte
  - - - Colour depth in bits per pixel
      - Resolution (Height and width in pixels)
      - Date created
      - Author
