Flowchart Symbols
Flowcharts use special shapes to represent different
types of actions or steps in a process. Lines and arrows
show the sequence of the steps, and the relationships
among them. These are known as flowchart symbols.
The type of diagram dictates the flowchart symbols that
are used. For example, a data flow diagram may contain
an Input/Output Symbol (also known as an I/O Symbol),
but you wouldn't expect to see it in most process flow
diagrams.
Over the years, as technology has evolved, so has
flowcharting. Some flowchart symbols that were used in
the past to represent computer punchcards, or punched
tape, have been relegated to the dustbin of history.

Start/End Symbol
The terminator symbol marks the
starting or ending point of the
system. It usually contains the
word "Start" or "End."
Action or Process Symbol
A box can represent a single step
("add two cups of flour"), or and
entire sub-process ("make bread")
within a larger process.
