We just learned about the Power Supply.

Another part of a computer is Bluetooth.

We know that you can hook things up to your computer like your monitor, or plugs things into USB ports.
But sometimes you might have a keyboard, mouse or headphones that are wireless and don't plug into anything.

For things like that you can use something called Bluetooth, which is a way for your computer to talk to other things using radio waves on a certain channel.
If you want to hook up a bluetooth mouse, it's kind of like both your computer and your mouse have to turn on the radio and listen to the same station.
Once they are on the same station they know how to talk to each other, and the mouse can send message to the computer to move the cursor around.

The Bluetooth name comes from an old Scandinavian king named Harald Bluetooth, who helped bring Danish tribe together into one kingdom.
This was supposed to mean that the Bluetooth way of wireless radio could be the way to help bring other technologies together.
The symbol that kind of looks like an xB is the symbol of the King.
