An external command in computers is a type of program that you can run from a command line interface, but it’s not built into the operating system itself. These commands are stored as separate files, usually in specific folders that the operating system knows to look in when you type a command.

Unlike internal commands that are already loaded into the command processor, external commands need to be loaded from a disk when you call them. This means they can be updated or changed without affecting the core operating system. They’re used for a variety of tasks, such as managing files, checking the health of your system, or setting up network connections. External commands give users and system administrators more tools to manage and troubleshoot their computers effectively.
