The answer: B) Scanner
When working with computers, it’s important to recognize what devices can get information in and send information out. Some common input devices are keyboards and mice, but it’s also useful to be familiar with others. As an input device, scanners are designed to take printed materials and create digital representations of them.
The incorrect answers:
A) LCD monitor
An LCD monitor displays information from the computer for humans to see, so it clearly qualifies as an output device.
