When you use a computer or the internet, you often have to give permission to access certain things, like your personal information or files. This permission is called a "privilege".
Now, let's imagine your computer is like a big playground, and you are playing with your toys in one corner of the playground. Your friends are playing in another corner. If one of your friends starts to misbehave and break the rules, the teacher might take away their toys or send them to the principal's office.
Similarly, if someone misuses their computer privileges, their access to certain things can be taken away. This is called "privilege revocation". For example, if someone uses their work computer to look at inappropriate content or to steal company information, their boss might take away their computer privileges by blocking access to certain websites or files.
Privilege revocation helps keep everyone safe and ensures that people use their computers and the internet responsibly.
