A network diagram shows the sequence of the task that is done to complete a project. It usually shows the link of each task with the duration taken by each activity with respect to the completion of the project. Each task is shown with the nodes that are connected with each other with the help of arrows. There are 2 types of network diagrams:- CPM and PERT.
