Universal Virtual Computer

Imagine you have a big box that can do lots of different things. This box is called a computer. Now, imagine there is another box that can do everything the first box can do, but is much smaller and can be used on different types of things, like your phone or your TV. This box is called a universal virtual computer.

So, a universal virtual computer is like a smaller version of a regular computer that can be used on lots of different things. It's like having a special tool that can work on different machines instead of needing a different tool for each one. This makes things more convenient and efficient.
