A virtual machine is flexible, as its physical form is a set of files, configuration file, and virtual disk files.
Virtual machines can be set up with virtual Network Interface Cards (NICs), which connect to virtual switches, creating a virtual network.
Virtualization is the abstraction of computing resources from the physical hardware, making it possible to run several operating systems on one computer.
