Flowcharts

Flowcharts

1. Terminator

   • The primary function of a terminator symbol is to clearly designate the beginning and end of a process.
   • It's typically represented by an oval or rounded rectangle, which visually distinguishes it from other flowchart symbols.
   • The symbol often contains the words "Start" or "End" to further clarify its purpose, although it can also depict a trigger action that starts the process.
   • When used as a "Start" symbol, it typically has only one outgoing arrow indicating the direction of the process flow, while a "Stop" or "End" symbol has only incoming arrows.

2. Input/Output

   • The parallelogram is the standard symbol used to represent input and output operations, signifying where data enters or exits a process
   • These symbols clearly indicate where data is being received (input) or presented (output) within the algorithm or process.

3. Decision

   • Decision points are represented by a diamond or rhombus shape.
   • They represent a decision or a question that needs to be answered, leading to different paths in the process.
   • Unlike other flowchart symbols that typically have one outgoing arrow, decision points have multiple arrows branching out, each representing a different possible outcome or path.

4. Process

   • help to document the various steps taken during the execution stage of a project
   • Typically the shape of a rectangle
