ELI5: Explain Like I'm 5

Multimachine

Multimachine is like having more than one machine to work on different tasks. Imagine you have a lot of work to do, like building a castle out of blocks or baking cookies. You can either do all the work by yourself or you can ask your friends to help you.
Similarly, a multimachine is like having friends who can help you do different jobs. It means having one big computer that can be divided into multiple smaller machines or computers, called virtual machines. Each virtual machine can do different jobs, like one can be used for video editing, one for browsing the internet, and one for playing games. The big computer controls all of them and makes sure they work together nicely.
Just like how your friends can come together and complete different parts of building the castle or baking cookies, a multimachine helps to do multiple jobs more efficiently by dividing them among the virtual machines.
