Coding and encoding


  • Data will be coded on collection so it can be entered easier
  • It makes data shorter so it is quicker to input
  • e.g. On a survey data entry may be a value between 1-5 instead of a description.


  • Converts data into machine readable form
  • The data that we use must be encoded into binary
  • Every letter is encoded into binary as this is all a computer understands
