A digital module normally can be designed in a format that composed of datapath part and controlpath part. Controlpath is mainly handle the control signal and state machine and Datapath is maiinly employed for data operations.
There are majorly 2 kinds of paths 1. clock path and the data path ... The Clock path is the path that the clock traverses before reaching your target point , Data path is the path taken by the Data to reach your end point ( typically a flipflop). Hope this clears ur doubts
