Question

What will be an ideal response?

Answer 1

Virtualization is the process by which one physical computer hosts many different virtual computers within it. One operating system, called the host operating system, runs one or more operating systems as applications. Those hosted operating systems are called virtual machines (vm). Each virtual machine has disk space and other resources allocated to it. The host operating system controls the activities of the virtual machines it hosts to prevent them from interfering with one another. With virtualization, each vm is able to operate exactly the same as it would if it were operating in a stand-alone, nonvirtual environment.
There are three types of virtualization:
PC virtualization-With PC virtualization, a personal computer, such as a desktop or laptop, hosts several different operating systems.
Server virtualization-With server virtualization, a server computer hosts one, or more, other server computers.
Desktop virtualization-With desktop virtualization, a server hosts many versions of desktop operating systems.
