How to determine the flow of data through a network and identify process logic?

What is a flowchart? Is a graphical representation of an

algorithm or of a portion an algorithm. Drawn using certain special-purpose

symbols. Rectangles Diamonds Ovals Small Circles

These symbols are connected by arrows called flowlines.

Symbols

Rectangle Also called action symbol Indicates any type of action including a

calculation or an input/output operation

Add 10 to Grade

Flowlines (Arrows)

Indicate the order in which the actions are to be performed.

Ovals

Contains the words Start/Begin Stop/End

Start

Small Circles

Also called connector symbols

A

Diamond

Also called the decision symbol Indicates a decision is to be made

NO

Yes

Grade < = 59

Input/Output

Represents data that is available for input or resulting from processing.
