Which of the following is a common portable device?

• A. Keyboard
• B. Mouse
• C. Printer
• D. Chromebook

Answer: (D)

Mobility and self-contained operation define a portable device. A device you can take with you and use away from a fixed setup must include its own power source, display, and input methods. Among the options, the Chromebook fits this description: it’s a laptop-style computer with a built-in screen, keyboard, and battery, designed to be carried and used on the go. The keyboard by itself is just an input accessory, not a standalone computing device. The mouse is also an input device. The printer is an output device and typically stays in one place; while there are portable printers, it’s not the common portable device in everyday use. So the Chromebook is the common portable device.
