A Virtual Machine (VM) allows you to build a computer within a computer. It allows you to run multiple operating systems on the same machine. They are completely independent of the computer on which they run so they cannot access files on your primary computer but can connect to the network.
A Virtual Machine (VM) is a simulated environment created by virtualization. It is a virtual environment that functions as a virtual computer system with it’s own CPU, Memory, network interface, and storage, created on a physical hardware system located off- or on- premises.
