Which category would a projector belong to?

• A. Processing Unit
• B. Input Device
• C. Output Device
• D. Storage Device

Answer: (C)

A projector’s job is to display information to an audience by taking a processed video signal and turning it into visible light on a screen. That makes it an output device because its primary function is to present data from the computer to the outside world. It doesn’t gather data to input into the computer (that would be an input device), it doesn’t store data for later use (a storage device), and it doesn’t perform computations (a processing unit). While some projectors may have buffering or built-in speakers, these don’t change the core role of outputting visual content.
