File System
“File System” is method of storing and organizing computer files and the data they contain to make it easy to find and access them.
File Path
A file 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.
File Extension
A file extension, sometimes called a file suffix or a filename extension, is the character or group of characters after the period that makes up an entire file name. The file extension helps an operating system, like Windows or Mac OSX, determine which program on your computer the file is associated with.
Command Line
The command line is a text interface for your computer. It’s a program that takes in commands, which it passes on to the computer’s operating system to run. From the command line, you can navigate through files and folders on your computer, just as you would with Windows Explorer on Windows or Finder on Mac OS.

source code
Source code is the fundamental component of a computer program that is created by a programmer. It can be read and easily understood by a human being. When a programmer types a sequence of C language statements into Windows Notepad, for example, and saves the sequence as a text file, the text file is said to contain the source code.
