1. Dummy activities: Dummy activities are artificial activities added to a network diagram to maintain the logical relationships between other activities. They have zero duration and do not require any resources, but are necessary to accurately represent the sequence of activities in a project.
2. Total float: Total float, also known as slack, is the amount of time that an activity can be delayed without delaying the project completion date. It is calculated as the difference between the late start and early start times of an activity.
3. Independent float: Independent float is the amount of time that an activity can be delayed without delaying the early start of any successor activities. It is calculated as the difference between the late start of an activity and the early start of its successor activities.
4. Crashing: Crashing is a project management technique used to shorten the project duration by adding additional resources to critical path activities. This involves increasing the cost of the project in order to meet a specific deadline.
5. Dangling activities: Dangling activities are activities in a network diagram that have no logical relationship with any other activities in the project. They are not connected to the rest of the project and do not contribute to the completion of the project. Dangling activities should be identified and resolved to ensure the accuracy of the project schedule.

1. Dummy activities are non-value-adding activities that are added to a project network to maintain the logical precedence relationship between other activities. They represent dependencies between activities that do not actually require any work to be done, such as waiting for a material delivery or for a previous activity to be completed. Dummy activities have a duration of zero and do not consume any resources. They are used to ensure that the project schedule is valid and that all dependencies are accounted for.
2. Total float is the amount of time that an activity can be delayed without delaying the completion of the project. It is calculated by subtracting the early start time of an activity from its late start time. Total float represents the flexibility that the project manager has in scheduling the activity and can be used to identify critical activities, which have zero total float and must be completed on time to avoid delaying the project.
3. Independent float is the amount of time that an activity can be delayed without delaying any subsequent activities. It is calculated by subtracting the early finish time of an activity from its late finish time. Independent float represents the flexibility that the project manager has in scheduling the activity without impacting the schedule of other activities.
4. Crashing is a technique used to reduce the duration of a project by adding additional resources or incurring additional costs. Crashing is typically used for critical activities that are delaying the project and can be justified if the cost of crashing is less than the cost of delaying the project.
5. Dangling activities are activities that have no successor activities. They are typically the last activities in a project network and represent the end of the project. Dangling activities may indicate that there are missing dependencies or that the project scope is incomplete.
