Difference between Event and Activity in network diagram are as follows:
- Any individual operation, which utilizes resources and has a beginning and an end, is called an activity. The starting and ending points of an activity are referred to as events in network diagram.
- An event is that particular moment of time when a specific part of a project is to be completed, whereas an activity is the actual performance of a task.
- Activity is represented by an arrow to depict an activity with its head indicating the direction of progress in the project, whereas a circle is commonly used to represent event.
- Words like complete, start, issue, approves, taste, and so on are frequently used to describe events, while words such as design, process, test, develop, prepare, and so on represent activity.
