it uses eletrical energy
Usually, just heat energy. If there is no bread inside the toaster, you can see the light coming out of the heating elements. That is light energy. Ordinary bread toasters use resistive heating elements that emit heat energy (as contrasted to radio energy at around 2.4 GHz coming out of a microwave oven). So there should be no health danger to toast bread close by as long as you don't touch the heated surface.
Common household remote control devices typically use infrared light or radio frequencies.

Radio light. you can see by looking at the chart... http://abyss.uoregon.edu/~js/ast122/lectures/lec04.html
They all require electricity to function and are common household electronic devices used for different purposes.
Cooker. Refrigerator. Kettle. Toaster. TV. Radio. Computer. etc
Toasters and incandescent (old fashioned) light bulbs are very similar devices.Both of them use electric current passing through a wire to make the wire emitheat and light. In the light bulb, we use the light, and the heat is a nuisance.In the toaster, we use the heat, and we don't much care about the light.

nobody knows that you idiot -- potential, in an electric load-lifting crane -- kinetic, in a golf cart -- wind, in a fan -- chemical, in a battery charger -- radio, in a radio transmitter -- light, in an electric light -- heat, in a toaster
-- Any kind of radio ... with the possible exception of the simplest 'crystal set' ... comprises both series and parallel circuits. -- A flashlight is a series circuit. (Unless it's a new, modern one, with several LEDs putting out light. Then they're all in parallel.) -- The heaters in a toaster may be in either series or parallel.
They are all radio waves with frequencies lower than visible light.

It means it uses "Infrared" light instead of a "wireless" radio signal to connect to the computer.
Yes, if you have a radio on your computer there is a way to accomplish this.
The circuits have nothing in common. The dome light works whether or not the key is on, the radio only works with the key on.
