Have you watched some after searching it in youtube?

For computers it's separating the hardware layer from the software.

A tier 1 hypervisor installed on a computer lets you install other operating systems that essentially run as programs in the hypervisor. The hypervisor manages all the interactions with the hardware at near native performance.

This makes management, security, multi-user, multi-os, ect. easier.

For example, you need to log into your windows and linux machine and update and restart it.
With the hypervisor running on all your machines, from one place you can remotely view the machine, log in, update, and restart.

Another example, a service you are running on a machine is starting to slow down during peak hours...

With the hypervisor you can add more resources, eg, cores or ram, to the virtual machine or migrate it to another pool with more available resources.

Proxmox is free, give it a try. ESXi, Xen, Hyper-V are the big guys that can do some really complex stuff with buckets of cash of course. They have some free versions that do quite a bit as well. If you don't have a spare dedicated computer to run a hypervisor on you can run VMs from various companies on Win10. virtual box, vmware, etc.
