What type of commands are individual programs kept, as separate files on the hard disk (DOS diskette)? A. External B. Internal C. Change D. File E. None of the above

External
Internal
Change
File E. None of the above

The correct answer is: External.

External commands are individual programs that are kept as separate files on the hard disk (DOS diskette). They are not built into the operating system, and must be loaded into memory before they can be executed.

Internal commands are built into the operating system, and are therefore always available without having to be loaded into memory. They are typically shorter and simpler than external commands.

Change is not a type of command. It is a verb that means to make something different.

File is a noun that refers to a collection of data stored on a computer.

None of the above is not a valid answer.
