	[[Android (operating system)\|Android]] devices have the ability to run [[virtual machine]]s or [[Emulator\|emulate]] other [[operating system]]s. It does this either via [[desktop virtualization]], [[platform virtualization]], or emulation via [[compatibility layer]].		[[Android (operating system)\|Android]] devices have the ability to run [[virtual machine]]s or [[Emulator\|emulate]] other [[operating system]]s. It does this either via [[desktop virtualization]], [[platform virtualization]], or emulation via [[compatibility layer]].

	== Desktop virtualization ==
	[[Desktop virtualization]] apps are the least resource and space intensive compared to other virtualization types, since the Operating System that is being displayed on the Android device is actually located on another computer on the [[local network]] or elsewhere like on the internet.<ref>{{Cite web\|url=https://www.computerworld.com/article/3074236/now-you-can-run-windows-10-on-an-ipad-pro-android.html\|title=How to run Windows 10 on an iPad Pro or on Android\|last=Evans\|first=Jonny\|date=2019-01-28\|website=Computerworld\|language=en\|access-date=2019-11-20}}</ref> Depending upon how the desktop virtualization app works, they use [[Remote Desktop Protocol\|RDP]] or can use another protocol of their own. Most business oriented desktop virtualization apps require specific types of equipment or services in order for the app to fully function. For example, [[VMware Horizon View\|VMware Horizon Client]] requires specific VMware equipment for the app to work.<ref>{{Cite web\|url=https://www.vmware.com/products/horizon-apps.html\|title=Published Apps {{!}} Horizon Apps\|website=VMware\|language=en-US\|access-date=2019-11-20}}</ref>

	A major downside that desktop virtualization apps have compared to other types of virtualization or emulation technologies is that they require a network connection to the server as stated previously above.
