Okay kiddo, so tc is like a magic wand for Linux computers. It helps them control how data flows in and out of the computer. Just like how mommy and daddy might set a bedtime for you so you don't stay up too late, tc helps the computer set rules for how much data can come in and out of different places.
Let's say your computer has a really slow internet connection, and you want to make sure that your video call with grandma doesn't get interrupted. You can use tc to give your video call the most priority, like a special VIP pass, so it gets all the internet it needs while other things on your computer have to wait their turn.
Or maybe you're playing a really fun game online, but it keeps lagging because other people in the house are downloading big files. With tc, you can make sure that your game gets the most internet so it runs smoothly, while the big downloads have to wait their turn.
So tc is like a secret weapon that helps your computer control the flow of data, so you can have the best experience possible!
