1..A system flow chart, or data flow chart, is used to describe the flow of data through a complete data-processing system. Different graphic symbols represent the clerical operations involved and the different input, storage, and output equipment required. Although the flow chart may indicate the specific programs used, no details are given of how the programs process the data.
2..A program flow chart is used to describe the flow of data through a particular computer program, showing the exact sequence of operations performed by that program in order to process the data. Different graphic symbols are used to represent data input and output, decisions, branches, and subroutines

A flowchart is a diagrammatic representation that illustrates the sequence of operations to be performed to get the solution of a problem. Flowcharts are generally drawn in the early stages of formulating computer solutions. Flowcharts facilitate communication between programmers and business people. These flowcharts play a vital role in the programming of a problem and are quite helpful in understanding the logic of complicated and lengthy problems. Once the flowchart is drawn, it becomes easy to write the program in any high level language. Often we see how flowcharts are helpful in explaining the program to others. Hence, it is correct to say that a flowchart is a must for the better documentation of a complex program
4...The following are some guidelines in flowcharting:
In drawing a proper flowchart, all necessary requirements should be listed out in logical order.
A...The flowchart should be clear, neat and easy to follow. There should not be any room for ambiguity in understanding the flowchart.
B..The usual direction of the flow of a procedure or system is from left to right or top to bottom.
C...Only one flow line should come out from a process symbol.
