Okay kiddo, let's imagine that your family has a big cake for everyone to share. But, you and your little sister both want to cut the cake. Instead of fighting over who gets to hold the knife, your parents decide to have privilege separation.
Privilege separation means that different people get certain jobs or permissions to do things so that they don't accidentally mess with things that shouldn't be messed with - like your little sister cutting the cake!
In the same way, privilege separation for computers means that different software programs and users are given different levels of access to resources like the operating system or hardware. This helps to prevent unauthorized access or damage to the computer system.
For example, a regular user may only have permission to access certain files and programs, while an administrative user would have more access to make changes to the operating system and settings. This way, if something goes wrong, it's not as severe as if someone with more power accidentally messes it up.
So, just like how your parents made sure everyone could share the cake by giving different jobs to different people, privilege separation for computers helps keep things organized and secure!
