ELI5: Explain Like I'm 5

Hardware virtualization

Imagine you have a lot of toys to play with, but you only have one toy box. If you put all the toys in the toy box at once, you won't be able to play with them all. So, you decide to create a pretend toy box using a cardboard box. This pretend toy box looks and behaves like a real one, but it's not.

Hardware virtualization works the same way. Your computer has a lot of resources like CPU, memory, and storage, and it can do a lot of things at once. However, sometimes you want to use some resources for one purpose and others for a different purpose. Think of these purposes as different toys you want to play with.

Hardware virtualization allows you to create pretend boxes by using software. These boxes, called virtual machines, act like they have their own set of resources. You can install different operating systems, applications, and configurations for each virtual machine, and they will run independently of each other.

The physical resources of the computer are shared among these virtual machines, but the virtual machines are isolated from each other. It's like having different toy boxes for different types of toys. You can play with one set of toys without worrying about the others.

Hardware virtualization also provides a layer of security by isolating these virtual machines. It prevents malware or viruses from infecting the computer or other virtual machines.

In summary, hardware virtualization is like creating pretend toy boxes for your computer. It allows you to use different sets of resources for different purposes, and keeps everything safe and secure.
