  2. Tail and End event: An event that marks the starting of an activity called tail event and an event that marks the completion of an activity called end event.
  3. Dual Role event: An event that acts as both tail and end event is called a dual role event.
  4. Activity: It is the actual performance of the task which requires resources like time and cost for its completion.
  5. Duration of activity: Time taken for completion of a task is referred to as the duration of an activity.
  6. Dummy Activity: An activity that never requires any kind of resources called dummy activity.  These activities are introduced in the network to establish logical and grammatical relationships between different activities.
