What is the notation of a fork node?

• A. Line segment with one incoming edge and at least two outgoing edges
• B. Hollow diamond with a single incoming edge and at least two outgoing edges
• C. Line segment with two incoming edges and one outgoing edge
• D. Solid circle with one incoming edge

Answer: (A)

When modeling parallel tasks, a fork node splits one flow into several paths that run concurrently. The notation used for that is a line segment (a simple splitter) with one incoming edge and at least two outgoing edges. This captures the idea of starting multiple parallel activities from a single point. This is different from a decision point, which is shown as a hollow diamond and represents branching based on conditions. It’s also different from a join, which combines multiple incoming paths into one outgoing path. And a solid circle with one incoming edge doesn’t represent a fork in these diagrams.
