* : ''Virtualization is the process of running a virtual instance of a computer system in a layer abstracted from the actual hardware.'' Reference: https://opensource.com/resources/virtualization
* : The virtualized OS is installed and run in a window under another OS.
* Special software is used to manage the entire process, referred to as the '''hypervisor'''.<br><br>
* : '''Advantages''' of Virtualization:<ol><li>You can run VM from an '''ISO image file''' or a '''VM file'''.</li><li>One or more virtual machines can be run at the <u>same</u> time.</li><li>The '''guest''' OS '''shares hardware''' with the '''host''' OS and possibly other virtualized systems.</li><li>The '''guest''' systems have '''network access''' through the host.</li></ol>
* : '''Installation Tips:'''<ol><li>Virtualization requires a '''compatible processor''': not all processors support that feature.</li><li>Your '''BIOS''' should be set to '''<u>enable</u> Virtualization'''.</li></ol>
