Confidence in using paths helps with a surprising variety of more complex topics. The environment variable $PATH is a list of ordinary paths separated by colons. The shell uses it to search for program files to execute. Many programs use special variables to establish the base path for their operations; it is useful to know how to construct a path when one is called for as a command parameter.
We saw how paths feature in the absolute names of files. They also appear in URLs (Uniform Resource Locators, commonly associated with the World Wide Web). Paths may be one of the first things you learn, but their applications are endless.
