What is input/output?

by Zerus & Ona

what is input output

It may look like computers know how to do many different things! But, under the hood, we're always doing three basic tasks, over and over again.

  • [1] First, we receive signals from the outside world. And we refer to these signals or data as input.
  • [2] Once we receive any information, we store it in our memory to process it and do operations with it.
  • [3] When we have the result ready, we send the new data back. And we call output to the signals or data that we send back.

Explained like this, it may seem like it's very time-consuming, but you'd be surprised at how quickly we can process any of your inputs and send outputs back to you. We like to be always alert and listening to your messages!

Now that we know what input and output are, we'd like to share with you this story about what happened to a painter and his pixels.


Print this story at home and go through it while you cuddle up in bed. Or share it with all your students in the classroom.

Remember! Understanding computers is a SUPERPOWER. So, keep on learning! See you in the next episode!
