As a developer, I sometimes come across the term 'Critical Path' in the context of development execution. From wikipedia I know it has to do with identifying the necessary tasks that must be completed in a project.
Is my understanding correct?
What is the best definition of Critical Path you have encountered? How would identify the Critical Path when planning a project?

The definition of the critical path is: The shortest possible duration by which a set of tasks can be completed. It is represented by the longest summation of task durations given the required predecessor and successor relationships.
The critical path (or paths) is the longest path (in time) from Start to Finish; it indicates the minimum time necessary to complete the entire project.
The most common form of limitation is by critical path. All the activities on the critical path could be crashed and it still remains the critical path. There is no point in crashing alternative non-critical activities.
By default, Project shows only one critical path, the one that affects the project's finish date. But you might need to see more than one for a couple reasons: To make sure each subproject of a master project is on time. To track the progress of different phases or milestones.
For an Application:
The critical path is the sequence of activities (out of all the possible sequences within the application) which add up to the longest overall duration, and thus is the first target for optimisation.
For a Project:
The critical path is the sequence of project activities which add up to the longest overall duration. This determines the shortest time possible to complete the project.
