Command Prompt-

Definition - What does Command Prompt mean?

The command prompt (cmd.exe) is a native Windows application meant to act as a command-line interpreter. It was created by Microsoft for the OS/2, Windows CE and Windows NT-based operating systems, which includes Windows 2000, XP and currently Windows 8 as well as various server versions of Windows. It is not a DOS program but a real executable application. As the name suggests, the command prompt is used to issue various commands to the system, like file management commands such as copy and delete. It also acts as a user interface.
