How data tells a story

I learned that data is stored and produced in binary code. I also learned no data is ever truly erased if you don't use software to erase it and even then its not gone only hidden. I also found out that  data can be hacked and used to hurt you . If your home laptop or desktop is broken and you want to throw it away make sure to remove the heart drive and break it or burn it son no one can access your personal data.
