Command Prompt (CMD) is the Windows Command Processor and has been the command-line interface for Windows for decades. It originated from DOS and is considered a legacy tool at this point.

The command processor, TCC, is a superset of the one built into Windows. So, dir is still dir, and del is still del, and everything you already know about working in the command line is still valid.

The Command Prompt, aka CMD, is a command-line interpreter on your Windows PCs, the official name, however, is Windows Command Processor. You need to use a special syntax to put in your commands here.
