- Knowledge

- GIGO (Garbage in Garbage out)
- If you enter incorrect data into a computer, then the output from the computer will be incorrect
- Data can arise from:
- The results of an experiment, automatic measurements from sensors - temp, rainfall pressure. A transition - buying a download from internet, from a survey
