Ever wondered how the tiniest change in your computer’s memory could cause massive issues?
Well, that’s where a bit flip comes into play.
A bit flip is a phenomenon where a single binary digit (bit) in a computer’s memory changes its value from 0 to 1 or vice versa.
Cosmic rays
Cosmic rays are high-energy particles that originate from outer space and can penetrate the earth’s atmosphere and affect computing systems.
When cosmic rays collide with atoms in the atmosphere, they create secondary particles, including neutrons, which can cause bit flips in memory cells.
This phenomenon is more common at higher altitudes, and increases with altitude.

Must say I have never heard of this before When cosmic rays collide with atoms in the atmosphere, they create secondary particles, including neutrons, which can cause bit flips in memory cells.

Mostly this sort of thing is taken care of with software. You can tell if there is an incorrect byte and usually fix it if necessary. It depends on what the data stream is being used for.

Thanks for the link, sb, But I'm afraid it all just goes over my head. But that's fine. Mathematical I am not. It's strange saying that as one of my boys is an engineer.
