A Fingerprint Scanner.

A Fingerprint Scanner Is An Input Device As It Takes The Image And Gives It To The Program. It Can Be Used To Pay For Things. A Fingerprint Scanner Is Hardware Because You Can Touch It.

A Keyboard.

A Keyboard Is An Input Device Because You can Input The Keys. When The Keys Are Pressed The Sensor In The Computer Tells The Program You Are On That You Pressed That One Key.


A Printer Is An Out Put Object Because It Transfers From The Computer On To Paper.
