Flowcharts are a diagram that represents a process. They trace the steps of the process and included decisions and branches that the process might take. They are frequently used in the design stage of a product and are a useful tool to document and represent how a process or algorithm should flow or work.
FLOWCHART SYMBOLS
Flowcharts use different symbols to represent various actions, for example a diamond shape represents a decision in the process and will always have 2 possible outcomes which can be represented with YES or NO. whereas a parallelogram represents Data in flowchart. The image below shows many symbols that are used in flowcharts, however many of these are not used at GCSE, IB and A-level Computer Science. Commonly used symbols are discussed later.
