We just learned about the colors in
ROY G BIV.
You probably already know this, but
True is a way of saying Yes.
and
False is the opposite and means No.
A fancy word for
True and
False is
Boolean
named after the famous mathemetician
George Boole.
In computers and electronics, it's kind of like you're looking at a
light bulb.
If the light bulb is
ON, you can call that
True or Yes or even the number 1.
Is the light bulb is
OFF, you can call it
False or No or the number 0.

Inside computers the electricity that runs the computer has thousands
or even millions of little ones and zeroes, meaning
True and
False.
These little light bulbs are what make the pictures on your computer screen
and the light switches come from things like your keyboard and mouse.
You can imagine a room just filled with light bulbs and light switches,
and that's exactly what some of the oldest computers (like the
ENIAC) looked like!
