Virtual Everything

Virtual machines are very much useful and space friendly when it comes to multi computera. It's a machine on a machine without all the extra hardware. If you are an advanced user you would probably want to know this eagerly.
A virtual machine works on a CPU and works as multiple CPUs. If there is no extra hardware for the virtual machine it uses the hardware of the REAL machine. It's very helpful especially when you want to run other types of operating systems. You can also try many things on  a virtual machine. But a software like VMWare. These type of softwares help in the making of a virtual machine on which an OS is installed.
A virtual machine has a configuration less than the actual machine. You get to chose the configuration of the CPU including the RAM, the ROM, the processor type etc... You can run multiple operating systems at an instant that can be switched like multitasking. It's even possible to create these virtual machines on your high end android devices. I'm not sure it would work on a low end device (efficiently).
