A virtual machine (VM) is a software-based simulation of a physical computer that operates like a physical computer but is created within a host operating system. This 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 machine, and isolating applications for security purposes. They are also used in cloud computing environments to provide scalable and cost-effective solutions for businesses.
