Concept explainers

Concept of flowchart

A flow chart diagram is a collection of symbols that represents the steps involved in a process. It is a generic tool that can be adapted for various purposes. It is one of the most common process analysis tools. It is used for the graphical analysis of an algorithm. It helps to represent the flow of the process from the input to output. A flowchart that represents the workflow of activities is known as an activity diagram.There are so many ways that can help people to understand computer technologies and their applications. One of them is a flowchart diagram.
