Input hardware devices MCQ - Practice Questions with Answers

A keyboard and mouse are input hardware because they send data, commands, and control signals from the user to the computer. That matches the phrase 'from the outside world' in the stem. An output device sends processed information from the computer to the user, so it works in the opposite direction. A secondary storage device stores data for later use but is not mainly used to enter information or control signals. A TFT monitor is a display screen, so it is an output device rather than input hardware.
