I was thinking about my first contact with html language and I remembered when I was looking for that specific button with the dot. It gives you some choices and you can select only one of them. I found out that it was called a radio button. I had no idea about how the word 'radio' was related to something like this and I think it's time to solve the mystery.
So my question is ... why is it called a radio button?
This question may not have a specific purpose but I'm still curious.
Thanks
p.s. I had no idea about the tags I should use for the question so any suggestions for changes will be welcomed
