We just learned about the Bluetooth.
Another part of a computer is a Webcam.
Not that long ago, if you wanted to send a picture to your friend you had to put it in an envelope and mail it through the post office.
These days if you want to send a picture you can take one with your phone camera, or the camera hooked up to your computer.
Remmember that smart phones are actually tiny computers!
You can even have a live video with a friend and you can see them using the cameras on your computers.
When these cameras on computers first came out they were called Webcams, and they usually were a separate camera that you set up and plugged into your computer.
These days pretty much every laptop already has a camera in it, but sometimes people still want a fancy expensive camera to use for talking to their friends over the computer.
