Answer / Naman Goel
Application events are global events that can be fired by any Aura or LockerService component in your app. Component events, on the other hand, are custom events specific to a particular Lightning Component. Application events are useful for communication between components with no direct parent-child relationship, while component events allow for more targeted communication within a single component hierarchy.
