What shape in flowcharts typically represents input/output operations?

In flowcharts, the shape that represents input/output operations is a parallelogram. This shape is specifically used to denote actions where data is received (input) or provided (output), such as reading data from a user, showing results on a screen, or writing data to a file.

The use of a parallelogram helps to visually distinguish these operations from other types of processes or decisions in the flowchart. For example, a rectangle is typically used to represent a process or an action, and a diamond is used for decision points where a yes/no question is asked. A circle can denote the start or end of a flowchart, but it does not represent input/output operations.

This clarity in representation is essential for anyone interpreting the flowchart as it conveys exactly where data interactions occur in the processes being mapped out.
