Chapter 4 - Running Commands

• A cmdlet is a native PowerShell command-line utility. These exists only inside PowerShell and are written in a .NET Core language.
• A function can be similar to a cmdlet, but rather than being written in a .NET language, functions are written in PowerShell's own scripting language.
• An application is any kind of external executable, including command-line utilities such as ping, and ipconfig.
• Command is the generic term that we use to refer to any or all of the preceeding terms.
