Graphic Symbols and Charts

Design and Technology students are often required to produce and interpret data in graphic forms, such as diagrams, flow charts and so on. They are also required to understand a range of common graphic symbols.

Barcodes

  • Helps keep track of items while shipping and within stores;
  • Can establish which products are selling quickly;
  • Reduces shoplifting (thieves can’t switch price tags easily);
  • Inexpensive to implement;
  • Very accurate.
