Q. What is System Prompt?
On loading (or Switching to) DOS, the screen displays C :\>, C>, A :\> or a similar message. The message displayed by DOS is called DOS Prompt or System Prompt. This prompt serves two functions:
1. It point towards that DOS is ready to accept a command from the keyboard.
2. It displays the default drive name. For example, C>, C :\>, indicates that drive C: is a default drive. DOS will use the default drive for every file operations if the user does not identify any drive name with commands.
