Analyze Programming Problems and Flowchart Solutions Study Checklist
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.
Example of a Flowchart
Start
Stop
Enter Grade
Grade > = 60

How to describe the system development cycle?
The system development life cycle (SDLC) refers to the structure and stages used in the software development process from initial product conception through to product development and follow up maintenance.
