easyMultiple Choice
FC0-U71 Is an example of an input device? Practice Question
Which of the following is an example of an input device?
⚠ Common exam trap
It's easy for candidates to confuse input and output devices by focusing on the device's function in a general sense (e.g., a printer 'inputs' paper) rather than the direction of data flow relative to the computer, leading them to select output devices like monitors or printers as input devices.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Keyboard
A keyboard is an input device because it allows users to send data and commands to a computer by pressing keys, which are converted into electrical signals that the system processes. Input devices are defined as hardware components that provide data and control signals to a computer, and the keyboard is a classic example of this category.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Printer
Why it's wrong here
A printer receives data from the computer and produces output, making it an output device; input devices such as keyboards, mice, and scanners send data into the system. It is tempting because printers connect to and are controlled by the computer, but direction of data flow determines the category.
- ✗
Monitor
Why it's wrong here
A monitor displays rendered output, so it cannot feed data into the system as the question requires. It is tempting because monitors are ubiquitous peripherals, but they sit on the output side of the input/output divide, the opposite direction from the required device.
- ✓
Keyboard
Why this is correct
A keyboard is a peripheral that converts user keystrokes into electrical signals sent to the computer, making it an input device. It satisfies the stem's requirement by feeding data into the system, unlike output devices such as monitors or printers that present processed data.
- ✗
Speaker
Why it's wrong here
A speaker emits audio output, so it cannot supply data to the system; the question asks for an input device. It is tempting because speakers are common peripherals connected to computers, but they belong to the output category, the reverse direction of the required data flow.
