Getting Started with Virtual Machines: A Step-by-Step Guide

A virtual machine is a software-based emulation of a physical computer that can run an operating system and applications. It allows multiple operating systems to run on a single physical machine, providing flexibility and efficiency in resource utilization. Virtual machines are commonly used for testing software, running multiple operating systems on a single computer, and isolating applications for security purposes. They are also used in cloud computing environments to provide on-demand computing resources.
