SYSTEM FLOW CHART SYMBOLS                                                                               

Often System flow chart symbols are confused with program flow chart symbols. There is a big difference between these two types. 

System Flow Chart : This is the chart which is used to display how the "system" works on the whole. For 
   instance, the procedure of withdrawing cash from the ATM (Automated Teller Machine) should be displayed 
   using a system flow chart. It basically shows how the inputs and outputs are working and where data is being
   stored. Either in a document or on a disk. Such main details should be displayed with the aid of a system flow
   chart.
Program Flow Chart : This is the flow chart which displays the flow of the program inside the software which
   has been written. It shows what type of data is accepted or displayed, how the program control flows between
   the various entities of the algorithm. 
   See Program Flow Chart for more details.
