Virtualization

Virtualization is the process of, well, making something virtual.

You'll often hear about "Virtual Machines", but Virtual Machines are only a part of Virtualization.

The 3 big types of Virtualization are: Server, Network and Desktop Virtualization.

The first, Virtual Servers. ---

The second Virtual Networks. ---

Virtual Machines normally refer to the 3rd: Desktop Virtualization- A virtual Mac, Windows OS etc.

The biggest part of Desktop Virtualization allows you to essentially put a secure and pre-setup OS onto your new computer- Or multiple new computers, with ease.
