Heroku is a Platform as a Service (PaaS) product based on AWS, and is vastly different from Elastic Compute Cloud. Itâs very important to differentiate âInfrastructure as a Serviceâ and âPlatform as a Serviceâ solutions as we consider deploying and supporting our application using these two solutions.
A path, the general form of the name of a file or directory, specifies a unique location in a file system. A path points to a file system location by following the directory tree hierarchy expressed in a string of characters in which path components, separated by a delimiting character, represent each directory.
This rather simple path points to a file named File.txt located in the current directory (since the path lacks a directory-specification) on the current drive (since no drive specification is present). This path refers to the first serial port (COM1). This example uses a path containing slashes as directory separator.
