A flowchart is a graphical representation of an algorithm or a process, using various symbols to denote different types of actions or steps. It is widely used in computer programming and system design to visualize the flow of control and data through a system. Flowcharts help in understanding, analyzing, and communicating the logic of a program or process.

Symbols Used in Flowcharts

Flowcharts use specific symbols to represent different types of actions or steps. Here are some common symbols:

• Terminal (Start/Stop): Represented by an oval shape, it indicates the beginning or end of a flowchart.

• Process: Represented by a rectangle, it denotes an operation or action, such as a calculation or data manipulation.

• Decision: Represented by a diamond shape, it indicates a decision point where the flow can branch based on a condition.

• Input/Output: Represented by a parallelogram, it denotes an input or output operation.

• Flow Line: Represented by arrows, it shows the direction of the flow of control.

• On-page Connector: Represented by a small circle, it connects different parts of a flowchart on the same page.

• Off-page Connector: Represented by a small pentagon, it connects flowchart portions on different pages.
