Answer:
- Activities: Represent the actual work tasks that must be performed. They are usually shown as arrows (or on the arrow side of an activity‑on‑node diagram) and have a duration, cost and resource requirements.
- Dummy activities: Have zero duration and no resource consumption. They are used solely to show logical relationships (dependencies) that cannot be expressed by real activities alone, ensuring the diagram remains mathematically correct.
- Nodes (or events): Indicate the start or finish of one or more activities. In activity‑on‑node (AON) diagrams, nodes are the circles/boxes that hold activity identifiers; they mark points in time where the project’s state changes.
