Command Prompt is a command line interpreter application available in most Windows operating systems. It's used to execute entered commands. Most of those commands automate tasks via scripts and batch files, perform advanced administrative functions, and troubleshoot or solve certain kinds of Windows issues.
Command Prompt is officially called Windows Command Processor, but it's also sometimes referred to as ​the command shell or cmd prompt, or even by its filename, cmd.exe.
