Question

What are each of the following symbols in a flowchart? ? Oval ? Parallelogram ? Rectangle

Short answer

Answer: In a flowchart, the oval symbol represents the start and end points of the process, indicating where it begins and concludes. The parallelogram shape is used to represent input or output actions, such as data entry or displaying results. The rectangle symbol represents a process step or activity, which are the essential tasks or actions performed in the flowchart.

Step-by-step solution

Identify the Oval Symbol

In a flowchart, an oval symbol is used to represent the start and end points of the process. It is important to note the process starts and ends at these points. Always label the ovals with either "Start" or "End" to clearly indicate their function in the flowchart.

Identify the Parallelogram Symbol

The parallelogram shape in a flowchart is used to represent input or output actions in the process. These are typically steps where the user is required to enter data or information, or the system displays output or resulting information to the user after processing the data.

Identify the Rectangle Symbol

A rectangle in a flowchart represents a process step, also known as an activity or procedure. These are essential tasks or actions that need to be performed to accomplish the goal of the flowchart. For example, a rectangle may represent a step such as "Calculate Total Sales" or "Display Error Message".

Key concepts

Oval Symbol

In flowcharts, the oval symbol is fundamental as it marks the commencement and culmination of processes.
It simplifies understanding by clearly indicating where everything begins and ends.
This can be thought of as a powerful "Start" and "End" station for all operations in a flowchart.
Here's why this symbol is crucial:

• Starting Point: The process always starts with an oval symbol labeled "Start". This indicates the beginning of operations.
• Ending Point: The articulation of where processes conclude is also an oval, marked "End".

These create an easy-to-follow narrative, ensuring the flowchart's coherence.
Thus, ensuring clarity from initiation to the conclusion of a process.

Parallelogram Symbol

The parallelogram symbol plays a pivotal role in representing input and output events within flowcharts.
Think of this symbol as the communicative element of the process, signifying moments where interaction occurs. What makes the parallelogram essential?

• Input Actions: Whenever data input from a user or another source is required, a parallelogram is used. This could represent steps like "Enter User Details".
• Output Actions: When the system shares processed information, the same symbol is employed, as in "Display Results".

The parallelogram helps signal interactions, providing and receiving information vital for process completion.

Rectangle Symbol

In flowcharts, the rectangle symbol is used to denote a process step or action to be undertaken.
It breaks down a complex operation into manageable tasks, making flow easier to follow and understand. This is indispensable in detailing the flowline. Key points about the rectangle:

• Process Steps: It signifies the tasks or actions involved in operations. For example, "Process Order" or "Calculate Total" are typical rectangled steps.
• Activity Representation: By detailing tasks through rectangles, the flowchart conveys intricate processes clearly and sequentially.

This symbol is the workhorse of the flowchart, offering insight into the core functionalities and actions performed in the sequence.
