In general usage, a path is a route between two points. It may also be used metaphorically, as a philosophical route to a desired state or destination.
In Graph theory a path is a sequence of nodes of a graph where there is an edge from any node in the sequence to the following node. The first node in the sequence is called the path's start.
In computing a path is the general form of a file or directory name. In this example from MS Windows:
C:\windows\system is the path for the file sys32.dll.
See absolute path, relative path.
C:\windows\system\sys32.dll ,
