U.2

Okay, kiddo, so u.2 is like a tiny little room that helps computers talk to another type of room where we keep all of our important information.

It's kind of like we have a big house, but all of our toys (which are like files on a computer) are in a different room. u.2 is like a little hallway that connects our computer room to the toys room so we can easily get to all of our toys without having to run around the huge house.

This little hallway is really fast and can move a lot of information at once, so we can get to our toys really quickly and easily. Plus, it's really safe and secure, so no one else can get in and take our toys.
