Question

decide whether each of these items is an input device or an output device or both. drag the items into the correct categories webcam keyboard input devices usb flash drive monitor output devices speakers both scanner mouse i know it think i know it not sure no idea

Explanation:

A webcam captures video and sends it to the computer, a keyboard types in text and commands, so they are input devices. A USB flash drive stores data (can be seen as input when saving to it), but mainly used for storage not typical input - output like other devices here. A monitor displays information, so it's an output device. Speakers play audio, also an output device. A scanner reads images or text and sends to the computer (input), and a mouse is used to give commands to the computer (input).

Answer:

Input Devices: Webcam, Keyboard, Scanner, Mouse
Output Devices: Monitor, Speakers
Both: None
USB flash drive is mainly for storage and not strictly an input or output device in the traditional sense for this classification.
