Command Prompt is a feature of Windows that provides an entry point for typing MS DOS (Microsoft Disk Operating System) commands and other computer commands. The most important thing to know is that by typing commands, you can perform tasks on your computer without using the Windows graphical interface. Command Prompt is typically only used by advanced users.
