1.

The (a)   is used to represent either a starting point, or a

stopping point. This is easy to remember since you start every

single Logic Flow Chart with a circle containing the word Start

or Begin. Often you will end a Logic Flow Chart with an End

or Finish circle, but sometimes there is no end to the chart

and it simply begins again. This is the case with any circuits

that never turn off, but are always on and collecting data

2.

The (a)   is used to represent any action which has only

one outcome. For example, when a video game console is

turned on it always checks to see what video game is in it. It

does this every time after it starts up and it never checks in a

different way. This kind of action is represented by the square,

it never changes and there is always only one outcome.

3.

The (a)   is used to represent a question or actions with

more than one possible outcome. For example, once your

video game has loaded there is often a menu with a bunch

of options. This would be written in a Logic Flow Chart as

a diamond with something like the words “Start Up Menu”

written inside of it. Each action the user can take from this

menu would be represented by lines coming off the diamond

leading to another square, diamond, or circle. Maybe our

example Logic Flow Chart would have three options leading

away from the “Start Up Menu” diamond, one line to start a

new game, one to continue a saved game and another for

game settings. In the Logic Flow Chart each option is written

beside the line leading away from the diamond. It is possible

to have as many options as you like leading away from a

diamond in a Logic Flow Chart.

4.

The (a)   in a Logic Flow Chart connect all the different

pieces. These are there so the reader knows how to follow

the Logic Flow Chart. The lines often have arrows on them

and lead to whichever piece (circle, square, diamond) makes

the most sense next. The lines usually have explanation of

what has happened when they lead away from diamonds, so

the reader knows which one to follow.
