Which of the Following Are Considered Input Devices
Let's just get this straight from the start: an input device is anything you use to feed data into a computer. It’s the difference between you talking to your machine versus your machine talking back at you. Most people know the keyboard and mouse are input devices. But here’s what most folks miss — there’s a whole world of gadgets that slip through the cracks when you’re asked this question.
So which are actually considered input devices? Even so, the short version is: anything that sends information to a computer counts. That means keyboards, mice, scanners, microphones, cameras, touchscreens, and even some surprising ones like joysticks or barcode scanners. But not everything you might point to is an input device. Monitors and printers? Those are output devices. Which means speakers can be output, but a microphone plugged into the same system? That’s input.
Counterintuitive, but true That's the part that actually makes a difference..
What Is an Input Device?
At its core, an input device is hardware that lets you enter data into a computer system. Even so, the computer processes this data and generates some kind of result — whether that’s a document, a video, a calculation, or a response. Input devices convert physical actions or signals into digital information the computer can understand.
Think about typing this sentence. In real terms, your fingers press keys. The keyboard sends electrical signals. The computer interprets those as letters. That’s input in action.
Why This Question Actually Matters
You might think this is just a textbook quiz question. But understanding input devices matters more than you’d expect. So it shapes how you troubleshoot tech issues, choose the right gear for your workflow, or even design user interfaces. When you know what counts as input versus output, you stop making assumptions that cost you time or money.
To give you an idea, many people don’t realize that a webcam is an input device. So when their video call won’t connect, they’ll stare at their monitor (output) instead of checking if the camera (input) is working properly Took long enough..
The Real List of Input Devices
Let’s break down what actually qualifies.
Keyboards and Mice: The Basics You Can’t Ignore
These are the giants of input devices. Together, they’re the primary way most people interact with computers. A mouse lets you point, click, and drag. A keyboard lets you type text, enter commands, and manage systems. But don’t sleep on alternatives like trackballs, touchpads, or graphics tablets — they’re all input devices too.
Touchscreens: More Than Just Phones
Modern touchscreens blur the line between input and output. You look at them, sure. But you also touch them to enter data. Even so, that dual role makes them hybrid devices. Smartphones, tablets, kiosks, and some monitors use touchscreens that register your taps, swipes, and pinches as input.
Scanners and Cameras: Capturing the Physical World
A scanner takes a physical image or document and turns it into digital data. A camera does something similar with photos and video. Both convert real-world visuals into something a computer can process. These are essential for everything from photo editing to document management Not complicated — just consistent. That's the whole idea..
Microphones and Voice Input
With the rise of voice assistants and voice recognition software, microphones have become crucial input devices. Whether you’re dictating a memo, controlling your computer with voice commands, or joining a video call, sound input plays a bigger role than ever The details matter here..
Specialized Controllers: Beyond the Standard Setup
Joysticks, gamepads, and steering wheels are input devices if they connect to a computer. So are barcode scanners in retail systems. In practice, even some musical instruments with USB connections count. The key is whether the device sends data to a computer for processing.
Biometric Sensors: The Future on Your Finger
Fingerprint readers, facial recognition cameras, and voice biometrics are emerging input methods. They capture unique biological data to verify identity or authenticate users. As security becomes more important, these devices move from novelty to necessity Simple as that..
What Most People Get Wrong
Here’s where the confusion usually starts.
Monitors Aren’t Input Devices
This one trips up a lot of people. Because of that, a monitor displays output — text, images, video. Here's the thing — it doesn’t send data back to the computer. Some touchscreens blur this line, but a standard monitor is purely output.
Printers Are Output Devices Too
A printer receives data from a computer and produces a physical copy. That's why it’s output, not input. Same with speakers — they play sound, they don’t record it No workaround needed..
Smart Devices Can Be Both
This is where things get tricky. A smartphone has a touchscreen (input), a camera (input), a microphone (input), but also a display (output) and speakers (output). Modern devices often combine multiple input and output functions Easy to understand, harder to ignore. No workaround needed..
External vs. Built-In Doesn’t Matter
Whether an input device is built into a laptop or plugged in externally doesn’t change its classification. The built-in webcam on your laptop? Plus, input device. The external USB microphone on your desk? Also an input device.
Practical Tips for Identifying Input Devices
Need a quick way to sort them out?
-
Ask what happens when you use it. If your action results in new data entering the computer, it’s input It's one of those things that adds up. Took long enough..
-
Check the connection flow. Data flows from input devices toward the computer, not away from it.
-
Look at the purpose. If the device’s job is to collect or transmit information to the system, it’s input Worth keeping that in mind. Which is the point..
-
Test the opposite. If you unplug it, does something stop working that should be receiving information? That’s your clue And that's really what it comes down to..

Q: How about USB drives? A: Storage devices like USB drives are considered input when you use them to transfer data to a computer Took long enough..
The Bottom Line
Input devices are anything that lets you interact with a computer by sending information into it. Keyboards, mice, touchscreens, scanners, cameras, microphones, and specialized controllers all qualify. In real terms, monitors, printers, and speakers don’t. Modern devices often combine multiple functions, so context matters That's the part that actually makes a difference..
Understanding the difference isn’t just academic — it helps you troubleshoot faster, choose better equipment, and avoid common tech pitfalls. Next time you’re setting up a new device or diagnosing a problem, ask yourself: is this sending data in or receiving data out? That question will usually point you in the right direction.
Q: Is a touchscreen an input or output device? A: It is actually both. It acts as an output device by displaying visual information to you, and an input device by allowing you to interact with that information through touch Nothing fancy..
Q: Is a scanner an input device? A: Yes. A scanner takes a physical image or document and converts it into a digital format that the computer can process And that's really what it comes down to. That alone is useful..
