Detailed explanation-1: -Synchronization. A fork node is used to split a single incoming flow into multiple concurrent flows. It is represented as a straight, slightly thicker line in an activity diagram. A join node joins multiple concurrent flows back into a single outgoing flow.

Detailed explanation-2: -A Fork notation in a UML Activity Diagram is a control node that splits a flow into multiple concurrent flows. This will have one incoming edge and multiple outgoing edges. A join node is a control node that synchronizes multiple flows.

Detailed explanation-3: -A fork node is a control node that splits a flow into multiple concurrent flows. Think of it as starting multiple concurrent tasks. A decision node is a control node that chooses between outgoing flows.

Detailed explanation-4: -Click the Fork Node button. on Diagram Tools. Click, or click-and-drag, in the activity diagram to place the fork node bar at the intended location. Draw a source state and an incoming control flow coming into the fork node bar. Draw the target states and the outgoing control flows from the fork node bar.
