Flowchart and Symbols Flashcards
A diagram of the sequence of movements or actions of people or things involved in a complex system or activity.
A graphical representation of a computer program in relation to its sequence of functions (as distinct from the data it
processes).
Flowchart
The terminal symbol marks the starting or ending point of the system. It usually contains the word “Start” or “End.“
Start/End Symbol
This symbol represents an instruction to an
input or an ouput device.
Input / Output Symbol
This symbol is used to represent a group of program
instructions that perform arithmetic operations, or to
compare sort.
Processing Symbol
This diamond-shapes box denotes a point in program where more than one path can be taken. It is used to document points in the program where based upon various conditions.
Decision Symbol
This symbol used to represent an instructions or group of instruction that will alter, or modify operations such as control, Index register, initialization, switch setting and in indicating loops.
Preparation Symbol
This symbol is a specialized process symbol that represents a named operation or programmed step not explicitly detailed in the program.
Predefined Process Symbol
This is a non processing symbol, which is used to connect one part of a flowchart to another without drawing flow lines.
On-page Connector
This type of connector is used instead of the one page connector to designated entry to or exit from one page when a flowchart requires more than one page.
Off-page Connector
This symbol used to show direction of processing or data flow.
Flow Direction Indicators
What are 3 types of flowchart?
Sequential, Selection, Repetition
Steps are performed in strictly sequential
manner, each step being executed once.
This is the simplest method of control. It
is easy to develop and understand.
Sequential Flowchart
The execution of instructions by selection, wherein conditions for a series of alternative statements are evaluated to specify which instruction is to be executed.
Selection Flowchart
A Loop is used when it is desire to make the same calculation on more than one set of data. It consists of repeating a program, or a selection of programs, and substituting new data for repetition.
Repetition Flowchart
