The Evolution of Virtual Machines in Operating Systems: Past, Present, and Future

A virtual machine is a software-based emulation of a physical computer system. It allows multiple operating systems to run on a single physical machine, enabling users to run different applications and perform various tasks without the need for multiple physical machines. Virtual machines are commonly used in cloud computing, software development, testing, and server consolidation. They provide flexibility, scalability, and cost savings by allowing resources to be allocated and managed more efficiently.
