Welcome!Today we'll learn about flowcharts, a tool for planning processes step by step. They're widely used in IT to design systems logically. Let's dive in!
What is a Flowchart?A flowchart is a diagram that represents a process or workflow. It uses shapes like rectangles, diamonds, and arrows to show the sequence of steps in a task or decision-making process. Flowcharts are useful for identifying inefficiencies and ensuring clear communication.
Why Are Flowcharts Useful?Flowcharts help us visualise processes clearly, making it easier to spot problems or improve steps. They're used in IT for tasks like designing algorithms, troubleshooting systems, and explaining workflows to teams. They simplify complex ideas into easy-to-follow diagrams.
