How Input and Output Devices Help You Every Day

Published: 20 Jun 2025

Computers cannot work alone. They need help to take in information and show results. I/O devices use computers. Input devices send information, like when we type on a keyboard or click with a mouse. Output devices help us see or hear what the computer has done, like watching something on a screen or hearing sound through speakers. These tools make it easy for us to use computers every day. Here are complete information about input and output devices are include;

What Are Input and Output Devices?

Common I/O devices help a computer work properly. Input devices give data to the computer. Output devices show us the results. These tools make it easy for us to talk to computers. Here are the computer input output devices for students and the input & output devices list included and explained.

What Are Input Devices?

Input devices are tools that help us give instructions to a computer. They send data into the computer so it knows what to do. For example, when we type on a keyboard or move a mouse, we are using input devices. These tools tell the computer what we want, like writing a letter, opening a game, or drawing a picture. Without input devices, the computer wouldn’t know how to start any task.

Common Types of Input Devices

There are many devices we use to send information to a computer. These are called input devices. They help us tell the computer what we want it to do. Some input devices are used every day at school, at home, and even in offices.

Here are some input devices are include:

Keyboard: Used to typing letters, numbers & words in to the computer.
Mouse: Move to the pointer and click on things on the screen.
Microphone: Voice into the computer and record sound.
Scanner: Copies a photo or paper and puts it into the computer.
Webcam: Sends live video or pictures to the computer.
Touchscreen: Lets us touch the screen to choose or move things.
Joystick: Used mostly for playing games by moving in different directions.
Light Pen: A pen-shaped tool used to draw or select things on the screen.

What Are Output Devices?

Output devices show us what the computer has done. They help us see pictures, hear sounds, or get printed papers from the computer. For example, a screen shows words and pictures, and speakers play music or sounds. Output devices help us understand the computer’s work easily.

Common Types of Output Devices

Output devices help us see, hear, or get the result from a computer. When the computer finishes work, these devices show the answer. We use output devices every day to watch videos, listen to music, or print papers.

Here are output devices are include:

Monitor: Shows pictures, words, and videos on the screen
Printer: Prints text or pictures on paper
Speakers: Play sounds, music, or voices from the computer
Projector: Shows the computer screen on a big wall or screen
Headphones: Let us listen to sound privately without bothering others

Difference Between Input and Output Devices

Input & output devices help computers talk with us. Input devices give data into the computer, and output devices show results from it.

Input Devices

Input devices take data from the user and send it to the computer.
Input devices are given more like keyboard and mouse.
Without input devices, computers can’t get instructions.
Input devices start the communication.
Input devices work when we type, click, or speak to the computer.
Input devices are like our hands and eyes giving information.

Output Devices

Output devices take data from the computer & give to the user.
Output devices like monitors and printers.
Without output devices, we can not see or hear what the computer does.
Output devices finish the communication.
Output devices work when we see pictures, read text, or hear sounds from the computer.
Output devices are like our ears and mouth getting information.

Both devices work together to make computers easy to use.

Devices That Work as Both Input and Output

Some devices can do both jobs. They can send data to the computer and also receive output from it. Here are some devices that both work.

Touchscreen: You can touch to give input and also see the output on the same screen
Headset: Has both a speaker and a microphone
Fax Machine: Sends and receives printed documents

Why Are These Devices Important?

Without input and output devices, computers cannot work with us. They help us give orders to the computer and understand what it shows. These tools make computers useful for learning, games, and work.
