- Name two input devices and two output devices.
- What should you check before assuming a keyboard, mouse, or screen is broken?
M00D - Input, Output, and Peripherals
Recognize how input, output, peripherals, and connected devices fit into the computer model before troubleshooting them.
Computer Basics
Input, Output, and Peripherals
Recognize how input, output, peripherals, and connected devices fit into the computer model before troubleshooting them.

Before this lesson
What you should learn
- Identify common input devices, output devices, and peripherals.
- Explain why a peripheral can fail even when the computer itself is still working.
- Separate device, cable, port, setting, and app issues before changing anything.
Visual model
Computer to operating system to action
Keep these layers separate before you troubleshoot. Most beginner mistakes come from changing a setting before naming the layer.
Open the full visualThe outside parts still belong to the computer story
Input and output are how the computer exchanges information with the outside world.
A peripheral is an extra connected device that extends what the computer can do.
Input
Input is what goes into the system.
Examples:
- keyboard presses
- mouse movement
- microphone audio
- webcam video
- touch input
Output
Output is what comes back out from the system.
Examples:
- text on the screen
- audio through speakers
- printed pages
- lights on a device
An output problem does not always mean the whole computer is broken. Sometimes the machine is working and only the output path is failing.
Peripherals and connected devices
Peripherals are often optional or add-on devices such as:
- mouse
- keyboard
- printer
- webcam
- headset
- external drive
These still matter because many real beginner problems start with a cable, port, power path, or missing driver.
Calm first question
When a device fails, ask first whether it is an input problem, an output problem, a connection problem, or a driver problem. That keeps the next step small and safe.
Before you move on
You are ready for the next lesson when you can explain:
- the difference between input and output
- what makes something a peripheral
- why a device problem can be connection-related or driver-related
Learning loop
Recall it, check it, then practice it.
Do this before moving on. It turns reading into memory and safer action.
- I can decide whether a device is used for input, output, or both.
- I can list safe first checks for a peripheral problem.
Review again after 1, 3, 7, 14 days.
