MS DOS Internal & External Commands

DOS Commands are instructions to perform tasks on files and directories. They are case insensitive. And as you already know, file is the area where we store group of information or data, and collection of group of files is called a directory.  

The internal commands reside in COMMAND.COM, which loads into memory when the computer system is started; these commands do not reside on disk. The external commands are files that do reside on disk and have an extension of .COM, .EXE, or .BAT. Both command types are executed from the MS-DOS prompt.
