simplest explanation I can think of.

You know how people say data is “1s and 0s”?

What really means is data is a huge bunch of switches that are either up or down, on (1) or off (0).

Ok, so imagine a big board with like, 100 little light switches on it.

The switches make a code.

first switch up position is A.

Second switch up is B.

First and second switch BOTH up is C.

So on and so on. I can do different combinations of the switches being up and down, and that represents something in the computer code.

Whatever my switch combination is, that is the “data”.

So what if I erase all the data? Where does it go?

(we’re going to talk about actually erasing the data “zeroing it out” not just “deleting” it, clearing a table. That’s complex, ignore that)

Ok, so when I erase the data, I’m actually just resetting all the switches back to the “0” position.

Now, did the data “go” anywhere? The switches didn’t go anywhere.

All 100 switches are still on the board right?

But they no longer represent what they used to, because their coded message has been reset.

“WHATEVER THIS DATA WAS” has just been replaced with

“000000000000000000000000000000000000000”

on the code board.
