When I said internet, I am speaking in a broader term, It includes anything that connects to the internet for example, Facebook, Instagram, Twitter, YouTube, TikTok, WhatsApp, any other websites and so on.
If you care about yourself, you should read this.
Can you image this? you upload your personal pictures into Facebook (for example) just to have fun but later you realise that you don't want anyone to see those pictures so you delete them but they are still in the web somewhere floating. Someone can pay Facebook (for example) to get your images anytime in future. How do you feel about that?
But how, why?
Once you upload your info into the cloud, you can never delete those information ever. Even though they give you the option to delete your account or pictures. Once you put your info into their sites, your information will be stored into their computer, so now they have control over your information.
So what do they do when you hit delete button in your account?
In simple word, they will just deactivate your image or account so you or anyone else can't see them but they - Facebook, Instagram, Twitter, Google etc. - can still those info.
In programming term:
This is what happens when you hit that delete button.
"UPDATE table_user SET activeOrder = 0 WHERE user_id = '1000' "
Actual delete supposed to be:
"DELETE FROM table_user WHERE user_id = '1000' "
Here is the simple example of Cloud.
Here is how cloud looks like behind the scene.
These are the computer hard drives where you information are stored.
