Question

What is virtualisation ? discuss advantages of virtualisation with the help of example?

Answer 1

Virtualization is a combination of software and hardware engineering that creates Virtual Machines (VMs) - an abstraction of the computer hardware that allows a single machine to act as if it where many machines.

Without VMs: A single OS owns all hardware resources

With VMs: Multiple OSes, each running its own virtual machine, share hardware resources

Virtualization enables multiple operating systems to run on the same physical platform
