Ok before I continue, I understand that I may sound a completely handicapped because I don't know as much about coding/computers as a lot of people on this forum do and I apologize. Also, I do not intend to use this to hack games/blockland, I am just curious as to if this is a thing. The drawings aren't the best either, I am more concerned about the question than the drawings
Anyway, let me put this into picture form as well as word form
So, say like you have a video game lightbulb being power from another computer:

Let's say that the binary reads 1 as something showing light and 0 as dark, so it would look kinda like this:

My question is: Would it be possible to somehow override the 1's (power) being sent from the computer to the light bulb and change it to zero. So basically turn the lightbulb off without even touching the computer.
I ask this question because if we truly live in a computer simulated universe, where 1 represents light and 0 represents dakrness, who's to say we can't just change the 1's to 0's.
