| Terminal | used to mark the beginning or end of a program or major process |
| Input-output | used for any function that transfers data to or from the computer’s main memory (There are also special symbols that can be used to indicate the specific input or output device that was used.) |
| Decision | used to indicate branching. Branching occurs when the computer executes a different set of instructions based on some condition. |
| Connector | Used to show exit to, or entry from, another part of the flowchart. A letter is used inside the connector to show which exit connector is matched with witch entry connector. |
